Abstract

The reaction of 3-acylamino- and 3-alkoxybenzo[c]pyrilium perchlorates with hydrazine has been studied. It was discovered that the direction of the recyclization of the pyran ring depends on the type of substituent in position 3 and on the ratio of reactants. Derivatives of isoquinoline and benzo-2,3-diazepine were obtained.
