Carboxylate as a promising and valuable directing group has attracted a great deal of attention. However, employing it as a traceless direction group has rarely been reported. We developed the ruthenium-catalyzed amidation of substituted benzoic acids wit

Paragraph 0017-0020; 0031-0034, (2017/02/28)
The invention discloses a one-step synthetic method of meta-substituted N-arylbenzamide compounds. Transition metal ruthenium is used as a catalyst, and the meta-substituted N-arylbenzamide compounds are synthesized in one step through carboxy-based o-C-H functionalization/ decarboxylation coupling reaction of aromatic acid and phenyl isocyanate compounds. The method has the advantages that the raw materials are simple and readily available, the catalyst is cheap, the reaction operation is simple, the utilization rate of atoms is high, the method is environment-friendly and the like.

The rhodium-catalyzed amidation of substituted benzoic acids with isocyanates by directed C-H functionalization followed by decarboxylation to afford the corresponding N-aryl benzamides is demonstrated, in which the carboxylate serves as a unique, removable directing group. Notably, less common meta-substituted N-aryl benzamides are generated readily from more accessible paraor ortho-substituted groups by employing this strategy.
