Alkenylation of aldehydes with β-silyl ketones proceeded to afford β,γ-unsaturated ketones with skeletal rearrangement. The reaction mechanism involved tandem aldol/[1,4]-Brook/1,2-addition/ring cleavage of cyclopropane. [1,4] Brook rearrangement took place with complete inversion of configuration at the carbon center.
醛与 β-甲硅烷基酮进行烯基化,得到具有骨架重排的 β,γ-不饱和酮。反应机理涉及串联羟醛/[1,4]-Brook/1,2-加成/环丙烷开环。[1,4]布鲁克重排发生,碳中心构型完全反转。
