Abstract
Preparation and structure of 1,2,3-triazolo[1,5-a]pyridinium N2-dicyan omethylides 7a,b are described. Reaction with methyl propiolate gives trisubstituted indolizines 8a,b in good yield. Reaction of 7b with dim ethyl acetylenedicarboxylate gives a quinolizine 12. Copyright (C) 199 6 Elsevier Science Ltd
