Synthesis of some novel phenylfuro[3,2-d]pyrimidine glycosides derivatives with expected antimicrobial activity

Abstract

Reaction of ethyl 3-amino-5-phenylfuran-2-carboxylate 1 with benzoyl isothiocyanate gave 2,3-dihydro-6-phenyl-2-thioxofuro[3,2-d]pyrimidin-4-one. Compound 3 was reacted with benzyl chloride to afford 2-(benzylthio)-6-phenylfuro[3,2-d]pyrimidin-4-one 4 and also reacted with bromoglucopyranosyl to give S-glycoside 5. The cyclization of ethyl 3-amino-5-phenylfuran-2-carboxylate 1 using thiourea, aniline, and carbon disulfide gave phenylfuro[3,2-d]pyrimidine derivatives. The pharmacological properties for the synthesized compounds were reported.
