cleavage of three C–X bonds, including two inert C(sp3)–F bonds on bromodifluoroacetamides, while leaving C–C bonds intact. This strategy will undoubtedly further consummate the role of halo difluoro compounds and enrich both fluorine chemistry and pharmaceutical sciences.
首次公开了空前的S 8催化的溴二氟乙酰胺的选择性三裂解。在该策略中,以级联方案以良好或优异的产率获得了有价值的2-酰胺基取代的苯并咪唑,苯并恶唑和苯并噻唑。机理研究表明,通过选择性裂解三个溴二氟乙酰胺上的三个C–X键(包括两个惰性C(sp 3)–F键)原位生成C2源,而保持C–C键完整。无疑,该策略将进一步完善卤代二氟化合物的作用,并丰富氟化学和制药科学。
