Several novel naphtho[2,1-b]pyrano[2,3-d]pyrimidines, pyrano[3,2-e][1,2,4]triazolo[1,5-c]pyrimidines and their coumarin-3-yl derivatives were synthesized. Some of these derivatives exhibited pronounced antimicrobial activities.

Keywords:pyranopyrimidine derivatives, pyranotriazolopyrimidine derivatives, coumarin-3-yl-pyranotriazolopyrimidine derivatives, antibacterial activity
