Abstract

A novel, facile microwave-assisted route for the synthesis of imidazo[1,2-c]thieno[3,2-e]pyrimidines 4 in quantitative yields is reported. The intermediates 4-chlorothieno[2,3-d]pyrimidines 3 were synthesized under one-pot reaction conditions.

Key words

imidazo[1,2-c]thieno[3,2-e]pyrimidines - microwave irradiation - one-pot synthesis - 2-substituted-4-chloro thienopyrimidines
