An Expedient Synthesis of Benzo[h]quinazolin-4(3H)-one: Structure of Samoquasine A Revisited

Abstract

An expedient four-step synthesis of benzo[h]quinazolin-4(3H)-one (1) starting from 1-tetralone is reported. The claimed identity of samoquasine A with perlolidine (4) has been discussed in the light of the present synthesis.
