Synthesis of novel fused chromone–pyrimidine hybrids and 2,4,5-trisubstituted pyrimidine derivatives via ANRORC rearrangement

Abstract

A facile and versatile procedure for the synthesis of functionalized novel 2,5-diphenyl-5<italic>H</italic>-chromeno[4,3-<italic>d</italic>]pyrimidin-5-ol and (2,4-diphenylpyrimidin-5-yl) (2-hydroxyphenyl) methanone has been described.
