Comparative studies for selective deprotection of the N-arylideneamino moiety from heterocyclic amides: kinetic and theoretical studies

The kinetics, product analysis and theoretical studies for selective deprotection of N-arylideneamino pyridone, pyrimidinone and triazinone systems were carried out. Their reactivities were compared with each other and with related compounds previously studied. This reaction represents an efficient, clean and general synthetic procedure for the protection and selective synthesis of potential biologically active pyridines, pyrimidines and triazines and their derivatives.
