rearrangement of epoxy acylates via stable cation intermediates was found, and new methods for constructing chiral benzylic, vinylic, and acetylenic quaternary carbon centers were developed. During the study, the importance of the ionic nature of the O-metal bond in the intermediates of such epoxides was addressed. This method was applied to the asymmetric total synthesis of (S)-(+)-sporochnol A.
发现了(C(6)F(5)O)(3)Al通过稳定的阳离子中间体促进环氧酰化物重排的显着效果,并开发了构建手性苄基,乙烯基和炔基季碳中心的新方法。在研究过程中,研究了这类环氧化物中间体中O-金属键的离子性质的重要性。该方法适用于(S)-(+)-亚砜醇A的不对称全合成。
