Oxidative debenzylation of N-benzyl aromatic amines using DMSO as a non-toxic oxidant and catalyzed by TsOH gave Nphenylimines, which were spontaneously hydrolyzed to form anilines and benzaldehydes in good yields. This reaction employs mild, metal-free conditions. The conditions are also suitable for the debenzylation of benzylphenylethers.

A short and facile synthesis of a series of quinazolines and imidazo[1,2-c]quinazolines was accomplished in good yields via the novel reductive cyclization of 2-nitrobenzyl amines or 2-(2-nitrophenyl)imidazoles with ortho-ester, aldehydes or ketones promoted by TiCl4/Zn system. The structures were established by spectroscopic data and confirmed by X-ray analysis.
