NOVEL THREE-COMPONENT REACTION OF PERIMIDINES WITH 1,3,5-TRIAZINES AND CARBONYL COMPOUNDS IN POLYPHOSPHORIC ACID. AN EFFICIENT METHOD FOR <i>peri</i>-ANNELATION OF A CARBOCYCLIC AND PYRIDINE RING

Abstract

Methods have been developed for the synthesis of 1,3-diazapyrenes, 8(6)-aryl-6(8)-oxo-1,6,7,8-tetrahydro-1,3-diazapyrenes, and 1,3,7-triazapyrenes based on a three-component reaction of perimidines with 1,3,5-triazines and carbonyl compounds, benzonitrile, or vinyl butyl ether in polyphosphoric acid.
