Abstract
The reaction of some [1,2,3]triazolo[1,5-a]quinolinium 1,2, [1,2,3]tri azolo[5,1-a] isoquinolinium 3,4 and [1,2,3]triazolo[5,1-b]thiazolium 5 ,6 ylides with dimethyl acetylenedicarboxylate is described. Compounds as dimethyl pyrrolo[1,2-a]quinoline-1,2-dicarboxylate 19, dimethyl py rrolo[2, I-a]isoquinoline-2,3:dicarboxylate 20, no-2,3-dimethoxycarbon yl-1H-pyrido[1,2-a]quinoline 24, 2,3-dimethoxycarbonyl-4H-pyrido[2,1-a ]isoquinoline 25, and ethyl-5,6-dimethoxy-carbonylpyrrolo[2,1-a]thiazo le 14b, are formed.
