Abstract

Abstract: A convenient and efficient method for the synthesis of 2-acylbenzothiazoles from benzothiazoles and aromatic ketones using oxygen as oxidant is described. FeCl3·6H2O showed the best reactivity among the various iron salts investigated. Various functional groups were well tolerated under the optimized reaction conditions. [Copyright &y& Elsevier]

3. Iron-Catalyzed One-Pot 2,3-Diarylquinazolinone Formation from 2-Nitrobenzamides and Alcohols.

Author

Wang, Huamin, Cao, Xiangxiang, Xiao, Fuhong, Liu, Saiwen, and Deng, Guo-Jun

Subjects
*IRON catalysts, *QUINAZOLINONES, *CHEMICAL alcohol analysis, *BENZAMIDE, *RING formation (Chemistry), *CHEMICAL synthesis
Abstract

A novel approach for the synthesis of 2,3-diarylquinazolinones using iron as catalyst is described. Various 2-nitro-N-arylbenzamides reacted with benzylic alcohols to selectively give the corresponding products in the absence of external oxidant or reductant. [ABSTRACT FROM AUTHOR]
