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 Brønsted acid was the key to the high efficiency of this transformation under metal-free conditions.

Visible-light-induced C–S bond formation in the synthesis of 2,4-disubstituted thiazoles through cascade difunctionalization of acetophenone: a greener approach
A novel approach for the synthesis of 2,4-disubstituted thiazoles from methyl aryl ketones, N-bromo-succinimide (NBS), and thioamide in water as a green reaction medium through visible-light irradiation is reported.
