The microwave-induced three-component one-pot synthesis of 2-amino-3-carbethoxy-4-phenylpyrano[3,2-c]quinolin-5(6H)-ones (4a–l) from 4-hydroxyquinolin-2(1H)-ones, aromatic aldehydes and ethyl cyanoacetate was described. The detailed synthesis, structure analysis, and antimicrobial screening for the title compounds were also reported. Pharmacological screen(More)
A series of pyrimido[4,5-b]quinolin-2,4(1H,3H)-dione derivatives (5-deazaalloxazines) was synthesized by the reaction of various substituted 2-chloroquinolin-3-carboxylic acids with urea/thiourea. The structure of these newly synthesized compounds was characterized by standard spectroscopic and analytical techniques. The antimicrobial activities of the(More)
