Synthesis and structure of 2-phenyl-4-aryl-3,4,5,6-tetrahydrobenzo[h]quinazolines
摘要:
The reaction of 2-arylidene-1-tetralones 1 with benzamidine gave 2-phenyl-4-aryl-3,4,5,6-tetrahydrobenzo[h]quinazolines 2. Investigations on the tautomeric equilibria of 2 by IR, H-1- and C-13-NMR showed the compounds to exist predominantly in the tautomeric form 2A both in the solid state and in solution. Acetylation and oxidation of the heterocyclic ring of 2 provided further evidence for the structural assignment of the title compounds.
