Abstract
Preparation of 2-substituted 9-(diethylamino)-12-(4-chlorophenyl)-12H-chromeno[3,2-e][1,2,4]triazolo[1,5-c]pyrimidines is reported. Furthermore, 3-benzylideneamino-5-(4-chlorophenyl)-8-(diethylamino)-4-imino-3,4-dihydro-5H-chromeno[2,3-d]pyrimidine, 3-ethoxycarbonyl-12H-chromeno[3,2-e][1,2,4]triazolo[1,5-c]pyrimidine-2-one, ethyl 2-formylamino- and 2-acetylamino-4H-chromene-3-carboxylates were prepared. Structures of these compounds were established on the basis of IR, UV, 1H NMR, 13C NMR and MS data. The new compounds were evaluated for antimicrobial activities.
