C−H thioarylation of hydrocarbon buildingblocks is a highly desirable synthetic transformation because of its prevalence in various pharmaceuticals and organic functional materials. However, to date all the developments majorly rely on peroxide mediated transformations. Unfortunately, the harsh reaction conditions of these reactions cause severe functional group intolerance. To overcome these issues
1]propellane with heteroaryl sulfones acting as difunctional reagents, allowing the introduction of alkyl and heteroaryl units across bicyclo[1.1.1]pentane frameworks. It features a broad substrate scope and can be used to functionalize structurally complex natural products. Mechanistic investigations indicate the Cs2CO3 promoted homolytic cleavage of heteroaryl sulfone C–S bonds by light. Moreover
在这项研究中,我们开发了[1.1.1]丙烷的光诱导双官能化,杂芳基砜作为双官能试剂,允许在双环[1.1.1]戊烷骨架上引入烷基和杂芳基单元。它具有广泛的底物范围,可用于功能化结构复杂的天然产物。机理研究表明Cs 2 CO 3通过光促进杂芳基砜C-S键的均裂。此外,产物中的苯并噻唑基部分可以充当甲酰基前体,这表明由于醛能够进行多种有机转化,因此产物具有强大的可转化性。
