3-methylthiazolo[3,2-a]benzimidazole and 2-methylimidazo[2,1-b]benzothiazole, respectively, react with methyl propiolate to give 1:2-adducts which are characterized as methyl(Z)-11-(methoxycarbonyl)-3-methyl-10-thiazolo[3,2-a][1,5]benzodiazepinacrylate and methyl (z)-5-(methoxycarbonyl)-2-methyl-4-[1,4]diazepino[7,1-b]benzothiazolacrylate.
