strategy for the synthesis of tetrasubstituted olefins has been developed. This procedure is realized by a formal C–C σ-bond cleavage reaction of cyclic α,α-dithioketones and subsequent deprotection. Notable features of this approach include excellent yields, mild reaction conditions, a broad substrate scope, and operational simplicity.
已经开发了一种通过 umpolung 策略合成四取代烯烃的炔酮的新型 1,2-双官能化。该过程是通过环状 α,α-二
硫酮的正式 C-C σ-键裂解反应和随后的脱保护来实现的。这种方法的显着特点包括出色的收率、温和的反应条件、广泛的底物范围和操作简单。
