Abstract

A novel series of pyrido[4,3-d]pyrimidine and pyrido[4,3-d][1,3]oxazine derivatives were synthesized via tandem aza-Wittig and annulation reactions with the corresponding iminophosphoranes, aromatic isocyanate, and amines. All newly synthesized compounds were elucidated by considering the data of both elemental and spectral analysis.
