Abstract:

Azomethyne ylides generated from 3-alkylthio substituted l-alkyl-5-aryl-1,2,4-triazinium salts 4a-c on treatment with triethylamine undergo 1,3-dipolar cycloaddition with dimethyl acetylenedicarboxylate to give pyrrolo{[}2,1-f] {[}1,2,4]triazines, while 1-ethyl-5-phenyl-1,2,4-triazinium salts 1a,b bearing the C=C bond in the side-chain 3-alkynylthio substituent react with acetylenes to undergo either intermolecular 1,3-dipolar cycloaddition or intramolecular inverse electron demand Diels-Alder reactions.
