Self-Assembly of Disorazole?C1 through a One-Pot Alkyne Metathesis Homodimerization Strategy.

ABSTRACT: Alkyne metathesis is increasingly explored as a reliable method to close macrocyclic rings, but there are no prior examples of an alkyne-metathesis-based homodimerization approach to natural products. In this approach to the cytotoxic C2 -symmetric marine-derived bis(lactone) disorazole?C1, a highly convergent, modular strategy is employed featuring cyclization through an ambitious one-pot alkyne cross-metathesis/ring-closing metathesis self-assembly process.

Catalytic Z-selective cross-metathesis in complex molecule synthesis: a convergent stereoselective route to disorazole C1.

Project description:A convergent diastereo- and enantioselective total synthesis of anticancer and antifungal macrocyclic natural product disorazole C1 is reported. The central feature of the successful route is the application of catalytic Z-selective cross-metathesis (CM). Specifically, we illustrate that catalyst-controlled stereoselective CM can be performed to afford structurally complex Z-alkenyl-B(pin) as well as Z-alkenyl iodide compounds reliably, efficiently, and with high selectivity (pin = pinacolato). The resulting intermediates are then joined in a single-step operation through catalytic inter- and intramolecular cross-coupling to furnish the desired 30-membered ring macrocycle containing the critical (Z,Z,E)-triene moieties.

Total synthesis of (-)-CP2-disorazole C1.

Project description:The total synthesis of a bis-cyclopropane analog of the antimitotic natural product (-)-disorazole C(1) was accomplished in 23 steps and 1.1% overall yield. A vinyl cyclopropane cross-metathesis reaction generated a key (E)-alkene segment of the target molecule. IC(50) determinations of (-)-CP(2)-disorazole C(1) in human colon cancer cell lines indicated low nanomolar cytotoxic properties. Accordingly, this synthetic bioisostere represents the first biologically active disorazole analog not containing a conjugated diene or polyene substructure element.

One-Pot Production of RNA Nanoparticles via Automated Processing and Self-Assembly.

Project description:From the original sequencing of the human genome, it was found that about 98.5% of the genome did not code for proteins. Subsequent studies have now revealed that a much larger portion of the genome is related to short or long noncoding RNAs that regulate cellular activities. In addition to the milestones of chemical and protein drugs, it has been proposed that RNA drugs or drugs targeting RNA will become the third milestone in drug development ( Shu , Y. ; Adv. Drug Deliv. Rev. 2014 , 66 , 74 . ). Currently, the yield and cost for RNA nanoparticle or RNA drug production requires improvement in order to advance the RNA field in both research and clinical translation by reducing the multiple tedious manufacturing steps. For example, with 98.5% incorporation efficiency of chemical synthesis of a 100 nucleotide RNA strand, RNA oligos will result with 78% contamination of aborted byproducts. Thus, RNA nanotechnology is one of the remedies, because large RNA can be assembled from small RNA fragments via bottom-up self-assembly. Here we report the one-pot production of RNA nanoparticles via automated processing and self-assembly. The continuous production of RNA by rolling circle transcription (RCT) using a circular dsDNA template is coupled with self-cleaving ribozymes encoded in the concatemeric RNA transcripts. Production was monitored in real-time. Automatic production of RNA fragments enabled their assembly either in situ or via one-pot co-transcription to obtain RNA nanoparticles of desired motifs and functionalities from bottom-up assembly of multiple RNA fragments. In combination with the RNA nanoparticle construction process, a purification method using a large-scale electrophoresis column was also developed.

A phosphate tether-mediated, one-pot, sequential ring-closing metathesis/cross-metathesis/chemoselective hydrogenation protocol.

Project description:A versatile three-step, one-pot, sequential reaction protocol involving ring-closing metathesis, cross-metathesis, and chemoselective hydrogenation is reported. This phosphate tether-mediated process occurs without intermediate isolation, is chemoselective, and is governed by stereoelectronic properties innate to phosphate tethers, which ultimately act to preserve the integrity of the bisallylic, bicyclic phosphate for subsequent nucleophilic additions. Overall, this process can be used to efficiently generate advanced polyol synthons.

One-pot isomerization-cross metathesis-reduction (ICMR) synthesis of lipophilic tetrapeptides.

Project description:An efficient, versatile and rapid method toward homologue series of lipophilic tetrapeptide derivatives (herein, the opioid peptides H-TIPP-OH and H-DIPP-OH) is reported. High atom economy and a minimal number of synthetic steps resulted from a one-pot tandem isomerization-cross metathesis-reduction sequence (ICMR), applicable both in solution and solid phase methodology. The broadly applicable synthesis proceeds with short reaction times and simple work-up, as illustrated in this work for alkylated opioid tetrapeptides.

One-pot synthesis of dicyclopenta-fused peropyrene via a fourfold alkyne annulation.

Project description:A novel dicyclopenta-fused peropyrene derivative 1 was synthesized via a palladium-catalyzed four-fold alkyne annulation of 1,3,6,8-tetrabromo-2,7-diphenylpyrene (5) with diphenylacetylene. The annulative π-extension reaction toward 1 involved a twofold [3 + 2] cyclopentannulation and subsequent twofold [4 + 2] benzannulation. The structure of 1 is unambiguously confirmed by X-ray crystallography; 1 adopted a twisted geometry due to the steric hindrance of the phenyl rings and the hydrogen substituents at the bay regions. Notably, compound 1 exhibits a narrow energy gap (1.78 eV) and a lower LUMO energy level than the parent peropyrene without the fusion of the five-membered rings. In addition, the effects of the peri-fused pentagons on the aromaticity and molecular orbitals of 1 were evaluated by theoretical calculations. This work presents an efficient method to develop π-extended aromatic hydrocarbons with cyclopenta moieties.

One-pot DNA construction for synthetic biology: the Modular Overlap-Directed Assembly with Linkers (MODAL) strategy.

Project description:Overlap-directed DNA assembly methods allow multiple DNA parts to be assembled together in one reaction. These methods, which rely on sequence homology between the ends of DNA parts, have become widely adopted in synthetic biology, despite being incompatible with a key principle of engineering: modularity. To answer this, we present MODAL: a Modular Overlap-Directed Assembly with Linkers strategy that brings modularity to overlap-directed methods, allowing assembly of an initial set of DNA parts into a variety of arrangements in one-pot reactions. MODAL is accompanied by a custom software tool that designs overlap linkers to guide assembly, allowing parts to be assembled in any specified order and orientation. The in silico design of synthetic orthogonal overlapping junctions allows for much greater efficiency in DNA assembly for a variety of different methods compared with using non-designed sequence. In tests with three different assembly technologies, the MODAL strategy gives assembly of both yeast and bacterial plasmids, composed of up to five DNA parts in the kilobase range with efficiencies of between 75 and 100%. It also seamlessly allows mutagenesis to be performed on any specified DNA parts during the process, allowing the one-step creation of construct libraries valuable for synthetic biology applications.

Polymer immobilized Cu(I) formation and azide-alkyne cycloaddition: A one pot reaction.

Project description:During the polymerization of aniline using copper sulphate, act as an oxidizing agent, the in-situ synthesized Cu(I) ion catalyzed the cyclo-addition between azides and alkynes. This work represents the merging of two steps, synthesis of the catalyst and application of the catalyst, in a one pot reaction. The elimination of the separate catalyst synthesis step is economic in terms of cost and time. As aniline was used as one of the reactant components so there is no requirement to use additional base for this reaction that further eliminates the cost of the process. Again, the catalyst can be readily recovered by filtration and efficiently used for the several sets of reactions without any significant loss of catalytic activity.
