been explored in the synthesis of a wide range of highly useful heterocycles and α- functionalized ketones. The continuously growing demand of α,α-dibromoketones, as highly reactive and mild synthetic precursors/intermediates, to carry out selective organic transformations, prompted us to investigate their potential application for the synthesis of thiazolo[3,2-a]benzimidazoles. In this study, a remarkable
已经在合成各种高度有用的杂环和α-官能化酮中探索了利用α,α-二卤代羰基化合物作为α-卤代羰基化合物的合成等价物。α,α-二溴酮作为高反应性和温和的合成前体/中间体,用于进行选择性有机转化,其需求不断增长,促使我们研究其在噻唑并[3,2-a]苯并咪唑合成中的潜在应用。在这项研究中,描述了 α,α-二溴苯乙酮 5a-g 在开发一种通过避免使用催泪性 α-卤代酮来合成噻唑并[3,2-a]苯并咪唑 4a-g 的简便方案中的显着应用。尽管在这些条件下中间体化合物 6 脱溴的机制尚未得到证实,但已经提出了可能的途径。
