Abstract

Recently we reported a new synthesis of quinazoline ring starting from N-imidoyliminotriphenylphosphoranes and aromatic aldehydes. The proposed mechanism was proved by an indipendent synthesis of the 1,3-diaza-1,3-diene intermediates. These diene derivatives when heated either in xilene or benzene give quantitatively the corresponding 3,4-dihydroquinazolines.
