Organolithium-induced alkylative ring opening of N-sulfonyl-protected aziridinyl ethers is described. The reactions were efficiently carried out with a variety of organolithiums, providing a promising new strategy to unsaturated amino alcohols and ethers. Cis- and trans-1,4-dimethoxybut-2-ene-derived aziridines were prepared, and their propensity to undergo organolithium- induced alkylative desymmetrization
描述了有机锂诱导的N-磺酰基保护的叠氮基醚的烷基化开环。反应可以使用多种有机锂有效地进行,为不饱和氨基醇和醚提供了一种有希望的新策略。制备了顺式和反式-1,4-二甲氧基丁-2-烯衍生的氮丙啶,并详细说明了它们经受有机锂诱导的烷基化脱对称的倾向。后者氮丙啶的单一对映异构体的使用提供了对映纯不饱和氨基醚的途径。
