tert‐Butyl hydroperoxide (TBHP) served as the methylsourceunder metal‐free aerobicconditions in the oxidativeamination of a C(sp3)–Hbond to provide quinazolin‐4(3H)‐one and quinazoline derivatives.
Palladium-Catalyzed <i>Ortho</i>-Selective C–H Oxidative Carbonylation of <i>N</i>-Substituted Anilines with CO and Primary Amines for the Synthesis of <i>o</i>-Aminobenzamides
An efficient, one-pot strategy with high selectivity and high atom economy for the synthesis of o-aminobenzamides has been developed via palladium-catalyzed ortho-selective C–H oxidative carbonylation of N-substitutedanilines with CO and primary amines. A wide range of N-substitutedanilines and primary amines can be tolerated in this transformation to afford the corresponding o-aminobenzamides in
A new and facile IL-DMSO assisted method has been developed for the synthesis of biologically important cyclic guanidines like 2-aminobenzimidazole, 2-imino-4-quinazolinone, and 2-imino-5-benzotriazepinones at ambient temperatures. The desired products could be obtained by microwave irradiation(32) also, but at elevated temperatures. A plausible mechanism for catalysis has been proposed. (C) 2012 Elsevier Ltd.
