Synthesis of Boc-protected bicycloproline.

ABSTRACT: The synthesis of a highly constrained quaternary carbocyclic ?-amino acid, (+)-N-Boc-bicycloproline, has been achieved starting from sodium cyclopentadienylide. Key steps include a rhodium-catalyzed nitrenoid C-H insertion to install the tert-alkylamine and a ring-closing metathesis reaction to form the pyrrolidine ring.

The synthesis of a highly constrained quaternary carbocyclic α-amino acid, (+)-N-Boc-bicycloproline, has been achieved starting from sodium cyclopentadienylide. Key steps include a rhodium-catalyzed nitrenoid C-H insertion to install the tert-alkylamine and a ring-closing metathesis reaction to form the pyrrolidine ring. ...[more]

A One-Pot Selective Synthesis of N-Boc Protected Secondary Amines: Tandem Direct Reductive Amination/N-Boc Protection.

Project description:A one-pot tandem direct reductive amination of aldehydes with primary amines resulting in N-Boc secondary amines using a (Boc)(2)O/sodium triacetoxyborohydride (STAB) system is reported. The tandem procedure is efficient, selective, and versatile, giving excellent yields of N-Boc protected secondary amines even in those cases where the products are prone to intramolecular lactamization.

Potassium Boc-protected secondary aminomethyltrifluoroborates: synthesis and Suzuki-Miyaura cross-coupling reactions.

Project description:Seven potassium Boc-protected secondary aminomethyltrifluoroborates were prepared in a standardized two-step process. The Suzuki-Miyaura cross-coupling reaction was studied with this new class of nucleophiles, and a large variety of aryl and hetaryl chlorides provided the desired products in good to excellent yields, thereby allowing easy access to secondary aminomethyl substructures.

Synthesis of Enantiomerically Pure N-Boc-Protected 1,2,3-Triaminopropylphosphonates and 1,2-Diamino-3-Hydroxypropylphosphonates.

Project description:All possible isomers of 1,2,3-tri(N-tert-butoxycarbonylamino)propylphosphonate 6 were synthesized from the respective diethyl [N-(1-phenylethyl)]-1-benzylamino-2,3-epiiminopropylphosphonates 5 via opening the aziridine ring with trimethylsilyl azide (TMSN3) followed by hydrogenolysis in the presence of di-tert-butyl dicarbonate (Boc2O). [N-(1-phenylethyl)]-1-benzylamino-2,3-epiiminopropylphosphonates (1R,2R,1'S)-5a and (1S,2S,1'R)-5c were smoothly transformed into diethyl 3-acetoxy-1-benzylamino-2-[N-(1-phenylethyl)amino]propylphosphonates (1R,2R,1'S)-9a and (1S,2S,1'R)-9c, respectively by the opening of the aziridine ring with acetic acid. Transformations of [N-(1-phenylethyl)]-1-benzylamino-2,3-epiiminopropylphosphonates (1S,2R,1'S)-5b and (1R,2S,1'R)-5d into diethyl 3-acetoxy-1-benzylamino-2-[(1-phenylethyl)amino]propylphosphonates (1S,2R,1'S)-9b and (1R,2S,1'R)-9d were accompanied by the formation of ethyl {1-(N-benzylacetamido)-3-hydroxy-2-[(1-phenylethyl)amino]propyl}phosphonate (1S,2R,1'S)-10b and (1R,2S,1'R)-10d and 3-(N-benzylacetamido)-4-[N-(1-phenylethyl)]amino-1,2-oxaphospholane (3S,4R,1'S)-11b and (3R,4S,1'R)-11d as side products. Diethyl (1R,2R)-, (1S,2S)-, (1S,2R)- and (1R,2S)-3-acetoxy-1,2-di(N-tert-butoxycarbonylamino)propylphosphonates 7a-7d were obtained from the respective 3-acetoxy-1-benzylamino-2-[N-(1-phenylethyl)amino]propylphosphonates 9a-9d by hydrogenolysis in the presence of Boc2O.

Synthesis and Suzuki-Miyaura cross-coupling reactions of potassium Boc-protected aminomethyltrifluoroborate with aryl and hetaryl halides.

Project description:Potassium Boc-protected aminomethyltrifluoroborate, a primary aminomethyl equivalent, was synthesized successfully through a "one-pot" process. With this trifluoroborate, Suzuki-Miyaura cross-coupling reactions were investigated with a variety of both aryl and hetaryl chlorides in good to excellent yields.

Modification of Boc-Protected CAN508 via Acylation and Suzuki-Miyaura Coupling.

Project description:The cyclin-dependent kinase inhibitor, CAN508, was protected with di-tert-butyl dicarbonate to access the amino-benzoylated pyrazoles. The bromo derivatives were further arylated by Suzuki-Miyaura coupling using the XPhos Pd G2 pre-catalyst. The coupling reaction provided generally the para-substituted benzoylpyrazoles in the higher yields than the meta-substituted ones. The Boc groups were only utilized as directing functionalities for the benzoylation step and were hydrolyzed under conditions of Suzuki-Miyaura coupling, which allowed for elimination of the additional deprotection step.

Acid-Facilitated Debenzylation of N-Boc, N-Benzyl Double Protected 2-Aminopyridinomethylpyrrolidine Derivatives.

Project description:2-Aminopyridinomethyl pyrrolidines represent a class of highly potent and selective neuronal nitric oxide synthase inhibitors. Conditions for a Mitsunobu reaction of a naphthol and a hindered secondary alcohol were optimized to give good to excellent yields. A key step in the synthesis of these inhibitors is the deprotection of the benzyl group from the N-Boc and N-Bn double protected 2-aminopyridine ring at a late stage of the synthesis, which has been proven difficult in our previous syntheses. Acetic acid was found to facilitate the N-Bn deprotection.

Temperature-Controlled Conversion of Boc-Protected Methylene Blue: Advancing Solid-State Time-Temperature Indicators.

Project description:Cold-chain management is of high importance in preserving perishable products and in retaining quality. A visible marker on packages indicating complete maintenance of the cold chain assures safe consumption of products by end-users and assists in reducing waste. Time-temperature indicators (TTIs) are integrated markers that provide information about exposure of packages to adverse temperature and have been gaining increased attention by consumers. Here we present a methylene-blue-based derivative, N,N,N',N'-tetramethyl-N10 -Boc-phenothiazine-3,7-diamine (BocPTDA), that can be used as a solid-state organic TTI dye, exhibiting an irreversible change from colorless to blue green upon heating. The conversion properties, studied using a silicagel-coated plate, confirmed that BocPTDA undergoes a color change above 20 °C. At temperatures of 4 °C and below, no visible changes are exhibited, making BocPTDA a well-suited marker for monitoring abrupt temperature deviations indicating improper cold-chain management. Thus, application of BocPTDA-based TTI systems on packages could inform consumers about the cold-chain maintenance, assuring quality and safe consumption.
