Synthesis of tetrahydroquinazolines from 2-aminobenzonitriles and alkylidene malonates via 1,4-conjugate addition and an unprecedented rearrangement reaction

Abstract

An efficient methodology for the synthesis of highly diverse tetrahydroquinazoline scaffolds from 2-aminobenzonitriles and alkylidene malonates via 1,4-conjugate addition followed by an unprecedented rearrangement has been demonstrated. The methodology is further applicable for the synthesis of quinazolines and tetracyclic compounds. Some of the synthesized compounds exhibit photophysical properties.
