The reaction of some [1,2,3]triazolo[1,5-α]quinolinium 1,2, [1,2,3,]triazolo[5,1-α]isoquinolinium 3,4 and [1,2,3]triazolo[5,1- β]thiazolium 5,6 ylides with dimethyl acetylenedicaboxylate is described. Compounds as dimethyl pyrolo[1,2-α]quinoline-1,2-dicarboxylate 19, dimethyl pyrolo[2,1-α]isoquinoline 2,3-dicarboxylate 20, 1,1-dicyano-2,3- dimethoxycabonyl-[H-pyido[1,2-α]quinoline 24, 4,4-dicayano-2,3- dimethoxycarbonyl-4H-pyrido[2,1-α]isoquinoline 25, and 7-methyl-5,6- dimethoxy-carbonylpyrrolo(2,1-α]thiazole 14b, are formed.
