Reported here is the reactivity of mesoionic 1,3-dithiolium-4-olates towards strained alkynes, leading to thiophene cycloaddition products. In the process, the potential of these dipoles towards orthogonal reaction with azides, allowing efficient double ligation reactions, was discovered. A versatile process to access benzo[c]thiophenes, in an unprecedented divergent fashion, was developed and provides
这里报道的是1,3-二硫代4-油酸中离子对应变炔烃的反应性,导致噻吩环加成产物。在此过程中,发现了这些偶极子与叠氮化物发生正交反应的潜力,从而可以进行有效的双重连接反应。开发了一种以前所未有的分歧方式获得苯并[c]噻吩的通用方法,它为非常规的多芳族噻吩提供了新的入口。
