Wang, Xingyi; Zhu, Yue; Zhou, Tingting; Yang, Weiqing; Fu, Haiyan; Chen, Hua; Ma, Menglin published the artcile< Bromine-Mediated C-S Bond Formation: Synthesis of Thiazoles from α-Methylene Ketones by Using Oxone Oxidative System>, SDS of cas: 57493-24-0, the main research area is ethanone methanethioamide sodium bromide catalyst one pot bromination heterocyclization; thiazole preparation.
A novel method for the synthesis of various 2,4,5-trisubstituted thiazoles from methylketones and thiourea/thioacetamide/amidinothiourea using NaBr/Oxone oxidative system was developed. The three intimately connected advantages of this method, which form a whole, are that the reaction underwent a one-pot α-bromination/cyclization process, the use of more common methylene ketones as the raw material rather than α-halomethylene ketones and a cheap and easily available catalytic amount sodium bromide as the bromine source instead of stoichiometric bromine or NBS.
ChemistrySelect published new progress about C-S bond formation. 57493-24-0 belongs to class thiazole, and the molecular formula is C9H7N3O2S, SDS of cas: 57493-24-0.
