Synthesis of Some Derivatives of the 4H-pyrido[4',3':5,6] pyrano[2,3-d]pyrimidines

Abstract

An approach is proposed and methods for the synthesis of a series of derivatives of 4H-pyrido[4',3':5,6]pyrano [2,3-d]pyrimidine, in particular 4-S-alkylated products, which containing an alkyl-or arylamide moiety in their structure, for the microbiological screening.
