Multi-substituted pyrroles are synthesized from regiospecific aziridine ring-opening and subsequent intramolecular cyclization with a carbonyl group at the γ-position in the presence of Lewis acid or protic acid. This method is highly atom economica

Among the large number of structurally diverse alkaloids, 2,6-disubstituted piperidine and its analogs have often been targeted when exploiting new synthetic techniques perhaps because of their strong pharmacological properties. This review outlines

Lewis acid-mediated regio- and stereoselective nucleophilic addition of 2- or 3-substituted indoles to non-activated aziridine-2-carboxaldehydes in dioxane afforded 2-(indol-3-ylhydroxymethyl)aziridines whose ring opening with various nucleophiles re

The first expedient asymmetric synthesis of both enantiomers of 5,6-dihydrouracil-type marine natural products biemamides B and D was achieved from chiral 1-(α-methylbenzyl)aziridine-2-carboxylate. The key steps involved in the synthetic route are r

A short and stereoselective synthesis of conduramine F-1 and ent- conduramine E-1 derivatives have been achieved starting from d -mannitol using nucleophilic vinylation on imine. A concise sequence of vinylation at both ends of d -mannitol and follow
