Synthesis of New Fused Thieno[3,2-d]pyrimidines Based on Thieno[3,2-d][1,3]oxazine Derivative

Аннотация

A method was developed for the synthesis of new fused amines, thieno[3,2-d]pyrimidine derivatives, starting from the corresponding chloride and various amines. Isomeric triazolo[4,3-c]- and -[1,5-c]-pyrimidines were obtained. The absence of azidotetrazole transformation of fused tetrazolo[1,5-c]pyrimidine was revealed.
