A series of polysubstituted pyrimidines were synthesized from in situ generated α,β-unsaturated imines and the corresponding amidine or guanidine derivatives in a convenient one-pot procedure.
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.
