Regioselective synthesis of N-acetylureas by manganese(III) acetate reaction of 1,3-disubstituted thioureas
摘要:
Reactions of asymmetrical 1,3-disubstituted thioureas with manganese(III) acetate produce regioselective N-acetylureas. A mechanism for this novel transformation is proposed. (c) 2006 Elsevier Ltd. All rights reserved.
An effective method was explored for the one-potsynthesis of N-acylated urea derivatives by the reaction of substituted isothiocyanatobenzenes, primary amines and PIDA (phenyliodine (III) diacetate) in one-pot manner. Mild reaction conditions, short reaction time, high efficiency and readily accessible materials are the features of this method, making suitable and alternative for the preparation of
