Journal ArticleDOI
Efficient and Expeditious Protocols for the Synthesis of Racemic and Enantiomerically Pure Endocyclic Enecarbamates from N-Acyl Lactams and N-Acyl Pyrrolidines.
TL;DR: The protocol was demonstrated to be applicable to several ring sizes, compatible with different protecting groups, and to be mild enough to prevent racemization of Racemization-prone stereocenters.
Journal ArticleDOI
Heck reaction of endocyclic enecarbamates with diazonium salts. formal enantioselective syntheses of alkaloids (-)-codonopsine and (-)-codonopsinine, and the synthesis of a new c-aryl azasugar
TL;DR: In this article, the Heck reaction was used to synthesize pyrrolidine alkaloids (−)-codonopsine and codonopsinine, as well as a new C-aryl azasugar from a common 5-membered, enantiomerically pure endocyclic enecarbamate.
Journal ArticleDOI
Stereoselective synthesis of azanucleosides aza-stavudine (aza-D4T), aza-2′,3′-didehydro-3′-deoxyuridine (aza-D4U), and its hydrogenated analogues from an endocyclic enecarbamate
TL;DR: In this paper, the stereoselective synthesis of the aza-analogues of nucleosides stavudine (D4T) and dideoxyuridine (DDU) was accomplished in a very concise manner (3-4 step sequences) with high overall yields from a five-membered endocyclic enecarbamate employing phenylselenenyl bromide as an effective promoter.
Journal ArticleDOI

TL;DR: In the mechanism of cytotoxic action, halimane 1 interferes in two major phases of the cell cycle: in S phase, in which DNA synthesis occurs and where it is very sensitive to damage, and G2M phase which is the phase of preparation for mitosis and mitosis itself, showing apoptosis‐inducing properties.
Journal ArticleDOI
Efficient and Expeditious Protocols for the Synthesis of Racemic and Enantiomerically Pure Endocyclic Enecarbamates from N-Acyl Lactams and N-Acyl Pyrrolidines.
TL;DR: In this article, a mild, practical, and straightforward protocol for the construction of endocyclic enecarbamates starting from Nacyl lactams and N-acyl pyrrolidines is presented.
