Br?nsted acid-promoted thiazole synthesis under metal-free conditions using sulfur powder as the sulfur source

Ni, Penghui,Tan, Jing,Li, Rong,Huang, Huawen,Zhang, Feng,Deng, Guo-Jun

, p. 3931 - 3935 (2020/02/04)

A Br?nsted acid-promoted sulfuration/annulation reaction for the one-pot synthesis of bis-substituted thiazoles from benzylamines, acetophenones, and sulfur powder has been developed. One C-N bond and multi C-S bonds were selectively formed in one pot. The choice of the Br?nsted acid was the key to the high efficiency of this transformation under metal-free conditions.
