Synthesis of 2-Substituted Pyrano[2,3-d]Pyrimidin- 4(3H)-One Derivatives Using Iminophosphorane

Abstract

A new and facile route to synthesize 2-substituted pyrano[2,3-d]pyrimidin-4(3H)-ones derivatives using iminophosphorane from easily obtained starting materials was investigated and expanded.

Keywords:

• Iminophosphorane
• pyrano[2,3-d]pyrimidine
• synthesis
