Viehe’s salt in a novel one pot synthesis of pyrimidines
摘要:
A series of pyrimidine derivatives are synthesized from N-substituted lactams, and Viehe's salt. A short reaction sequence, good yields of the targeted heterocyclic compounds (44-67%), as well as their convenient isolation and purification are the distinct advantages of the reported protocol.
