A strategy for the synthesis of the anthelmintic kainic acid is described, involving an investigation of the cycloaddition reactions of some azomethine ylides obtained from the thermal ring opening of aziridines and 4,5-dihydro-1,2,3-triazoles, with
ADDITION D' AZIDES A DES OLEFINES TRISUBSTITUEES PAR DES GROUPEMENTS ELECTROATTRACTEURS
Ouali, Mohand Said,Vaultier, Michel,Carrie, Robert
, p. 1821 - 1828 (2007/10/02)
The reaction of benzyl, methyl and phenyl azide, with olefins substituted by three electron-withdrawing groups, has been studied.This reaction gives in certain cases only one triazoline (single orientation of the cycloaddition).In other cases, a mixture o
