Synthesis of Thieno[2,3-d]pyrimidines and Aminopyrimidines from 2-Alkoxy-5-cyano-4-thioxopyrimidine Intermediates
摘要:
beta-Chloro-alpha-cyanocinnamonitrile reacts in an one-pot reaction with potassium thiocyanate and alkanol to form 2-allcoxy-6-phenyl-5-cyano-1,4-dihydro-4-pyrimidinthions. The products were S-alkylated to yield thieno[2,3-d]pyrimidines on cyclization and aminopyrimidines an substitution of alkoxy and alkylthio groups.
