A straightforward, metal‐free multicomponent tandem cyclization/aromatization approach for the synthesis of naphthothiazoles and benzothiazoles has been described. This method employs α‐tetralone and cyclohexenones as the starting materials, styrene derivatives as a one‐carbon synthon, ammonium salt as the N source, elemental sulfur as the S source, and an oxidant. This approach offers a broad substrate scope, including α‐tetralone and cyclohexenones adorned with different functional groups, resulting in moderate to high yields of the desired products.

多组分串联环化/芳构化反应：获得2-取代萘并噻唑和苯并噻唑

描述了一种用于合成萘并噻唑和苯并噻唑的简单、无金属多组分串联环化/芳构化方法。该方法以α-四氢萘酮和环己烯酮为起始原料，苯乙烯衍生物为单碳合成子，铵盐为N源，单质硫为S源，氧化剂。这种方法提供了广泛的底物范围，包括带有不同官能团的α-四氢萘酮和环己烯酮，从而产生中等到高产率的所需产物。
