Benzotriazole as an Efficient Ligand in Cu-Catalyzed Glaser Reaction.

ABSTRACT: Benzotriazole has been established as an efficient ligand in Cu-catalyzed cross-coupling of terminal alkynes to form 1,3-dialkynes using CuI as the catalyst and K2CO3 as the base at room temperature in an open round-bottom flask. The established protocol has the following notable advantages: simple to handle, easy work-up, mild reaction condition, high substrate scope, requirement of less quantity of ligand and also Cu-catalyst, less expensive, and high reaction yield.

Tailored ligand acceleration of the Cu-catalyzed azide-alkyne cycloaddition reaction: practical and mechanistic implications.

Project description:Tris(heterocyclemethyl)amines containing mixtures of 1,2,3-triazolyl, 2-benzimidazoyl, and 2-pyridyl components were prepared for ligand acceleration of the copper-catalyzed azide-alkyne cycloaddition reaction. Two classes of ligands were identified: those that give rise to high reaction rates in coordinating solvents but inhibit the process when used in excess relative to copper and those that provide for fast catalysis in water and are not inhibitory in excess. Several "mixed" ligands were identified that performed well under both types of conditions. Kinetics measurements as a function of ligand:metal ratio and catalyst concentration were found to be consistent with an active Cu(2)L formulation. Since strongly bound chelating agents are not always the most effective, achieving optimal rates requires an assessment of the potential donor molecules in the reaction mixture. Simple rules are provided to guide the user in the choice of effective ligands and reaction conditions to suit most classes of substrates, solvents, and concentrations.

Highly-efficient and versatile fluorous-tagged Cu(I)-catalyzed azide-alkyne cycloaddition ligand for preparing bioconjugates.

Project description:A novel ligand (FBTTBE) for Cu(i)-catalyzed azide-alkyne cycloaddition (CuAAC) has been developed, which demonstrates not only superior catalytic efficiency but also the ease of removing toxic copper species. FBTTBE has also been successfully applied in the synthesis of radiometal-labeled peptide and antibody without observable transchelation with the non-radioactive Cu(i) catalyst.

Cu-Catalyzed Transannulation Reaction of Pyridotriazoles with Terminal Alkynes under Aerobic Conditions: Efficient Synthesis of Indolizines.

Project description:The Cu(I)-catalyzed denitrogenative transannulation reaction of pyridotriazoles with terminal alkynes en route to indolizines was developed. Compared to the previously reported Rh-catalyzed transannulation reaction, this Cu-catalyzed method features aerobic conditions and much broader scope of pyridotriazoles and alkynes.

Ligand-Mediated Regioselective Rhodium-Catalyzed Benzotriazole-Allene Coupling: Mechanistic Exploration and Quantum Chemical Analysis.

Project description:The ligand-controlled rhodium-catalyzed regioselective coupling of 1,2,3-benzotriazoles and allenes was investigated by DFT calculations. Because allylation can occur at either the N1 or N2 position of the 1,2,3-benzotriazole, the complete Gibbs free energy profiles for both pathways were computed. A kinetic preference emerged for the experimentally observed N1 allylation with the JoSPOphos ligand, whereas N2 allylation was favored with DPEphos. Analysis of the regiodetermining oxidative addition step by using the activation strain model in conjunction with a matching energy decomposition analysis has revealed that the unprecedented N2 reaction regioselectivity is dictated by the strength of the electrostatic interactions between the 1,2,3-benzotriazole and the rhodium catalyst. The nature of the electrostatic interaction was rationalized by analysis of the electrostatic potential maps and Hirshfeld charges: a stabilizing electrostatic interaction was found between the key atoms involved in the oxidative addition for the N2 pathway, analogous interactions are weaker in the N1 case.

Cu-Catalyzed Azide-Alkyne-Thiol Reaction Forms Ubiquitous Background in Chemical Proteomics Studies

Project description:We report here a Cu-catalyzed azide-alkyne-thiol reaction forming thiotriazoles as the major by-product under widely used bioorthogonal protein labelling “click” conditions. The development of Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) had tremendous impact on many biological discoveries. However, the considered chemoselectivity of CuAAC is hampered by high reactivity of cysteine free thiols yielding thiotriazole protein conjugates. The reaction by-products generate false positive protein hits in “functional” proteomic studies. The reported detail investigation of conjugates between chemical probes containing terminal alkynes, azide-tags and cell lysates reveals formation of thiotriazoles, which can be readily detected by in-gel fluorescence scanning or after peptide and protein enrichment by MS-based proteomics. The produced fluorescent bands or enriched proteins may not result from the important enzymatically driven reaction and can be falsely assigned as hits. This study provides a complete list of the most common background proteins. The knowledge of this previously overlooked reactivity now leads to improved experimental design. Here, we present modified CuAAC conditions, which avoids the undesired product formation and diminishes the background.

Mild and efficient cyanuric chloride catalyzed Pictet-Spengler reaction.

Project description:A practical, mild and efficient protocol for the Pictet-Spengler reaction catalyzed by cyanuric chloride (trichloro-1,3,5-triazine, TCT) is described. The 6-endo cyclization of tryptophan/tryptamine and modified Pictet-Spengler substrates with both electron-withdrawing and electron-donating aldehydes was carried out by using a catalytic amount of TCT (10 mol %) in DMSO under a nitrogen atmosphere. TCT catalyzed the Pictet-Spengler reaction involving electron-donating aldehydes in excellent yield. Thus, it has a distinct advantage over the existing methodologies where electron-donating aldehydes failed to undergo 6-endo cyclization. Our methodology provided broad substrate scope and diversity. This is indeed the first report of the use of TCT as a catalyst for the Pictet-Spengler reaction.

Pinpointing the active species of the Cu(DAT) catalyzed oxygen reduction reaction.

Project description:Dinuclear CuII complexes bearing two 3,5-diamino-1,2,4-triazole (DAT) ligands have gained considerable attention as a potential model system for laccase due to their low overpotential for the oxygen reduction reaction (ORR). In this study, the active species for the ORR was investigated. The water soluble dinuclear copper complex (Cu(DAT)) was obtained by mixing a 1?:?1 ratio of Cu(OTf)2 and DAT in water. The electron paramagnetic resonance (EPR) spectrum of Cu(DAT) showed a broad axial signal with a g factor of 2.16 as well as a low intensity Ms = ±2 absorption characteristic of the Cu2(?-DAT)2 moiety. Monitoring the typical 380 nm peak with UV-Vis spectroscopy revealed that the Cu2(?-DAT)2 core is extremely sensitive to changes in pH, copper to ligand ratios and the presence of anions. Electrochemical quartz crystal microbalance experiments displayed a large decrease in frequency below 0.5 V versus the reversible hydrogen electrode (RHE) in a Cu(DAT) solution implying the formation of deposition. Rotating ring disk electrode experiments showed that this deposition is an active ORR catalyst which reduces O2 all the way to water at pH 5. The activity increased significantly in the course of time. X-ray photoelectron spectroscopy was utilized to analyze the composition of the deposition. Significant shifts in the Cu 2p3/2 and N 1s spectra were observed with respect to Cu(DAT). After ORR catalysis at pH 5, mostly CuI and/or Cu0 species are present and the deposition corresponds to previously reported electrodepositions of copper. This leads us to conclude that the active species is of a heterogeneous nature and lacks any structural similarity with laccase.

Cu-Catalyzed Asymmetric Aminoboration of E-Vinylarenes with pivZPhos as the Ligand.

Project description:A Cu-catalyzed enantioselective aminoboration of E-vinylarenes with pivZPhos as a ligand is reported. Enantioenriched aminoborates are prepared with excellent regio- and enantioselectivities up to >99:1 er under the optimized conditions. The utility of the current method was further established by rapid conversion of an adduct to a chiral benzo[f][1,4]oxazepine. A model for the stereochemistry of the asymmetric aminoboration process, which agrees with the experimental outcomes, was generated by computational analysis of the systems.
