Abstract

Methods of the preparation of 9- (methylsulfanyl)cyclopenta[4',5']pyrido[3',2':4,5]thieno[3,2-d]- pyrimidines and pentacyclic triazolopyrimidines derivatives were developed. The Dimroth rearrangement of these compounds was studied.

Keywords

fused thieno[3,2-d]pyrimidines, Dimroth rearrangement, triazolopyrimidines
