Journal ArticleDOI
The first synthesis of the ABCD ring system of manzamine A. Construction of the macrocyclic ring D.
TL;DR: In this paper, the synthesis of the ABCD ring system of manzamine A has been achieved using the olefin metathesis cyclization reaction for the crucial macrocyclic ring D formation step.
Journal ArticleDOI
Synthesis mediated by ring-closing metathesis : applications in the synthesis of azasugars and alkaloids
TL;DR: The application of the ring-closing metathesis (RCM) reaction to the construction of a wide variety of nitrogen-containing ring systems is described in this article, where the examples include pyrrolizidine, indolizidine and quinoline derivatives related to azasugars.
Journal ArticleDOI
A novel strategy for the synthesis of medium-sized lactams.
TL;DR: A novel method for the synthesis of medium-sized lactams based on an auxiliary-mediated combined tethered/templated strategy is presented to give seven- to ten-membered lactams in good yields.
Journal ArticleDOI
Models of folate coenzymes—VII : Synthesis and carbon transfer reactions of N5,N10-methenyl and N5,N10-methylenetetrahydrofolate models
TL;DR: In this article, Carboxylate esters react with 1,2-diaminoethanes to yield imidazolines, which upon consecutive reaction with acetic anhydride or tosyl chloride and methyl iodide give imidaziolinium salts that serve as models of N5,N10-(CH+)-tetrahydrofolate (THF) coenzymes.
