TsNClNa and t-BuSO(2)NClNa, BusNClNa) has been explored. The stereoselectivity of these reactions was highly dependent on the structure of the allylic alcohol and the chloramine salt. Generally, mixtures of cis- and trans-hydroxy aziridines were obtained, in which the major diastereomer was the cis-hydroxy aziridine, whilst complete cis-diastereoselectivity was observed in the aziridination of 1,3-disubstituted
已探索了使用两种不同的氯胺盐(4-MeC(6)H(4)SO(2)NClNa,TsNClNa和t-BuSO(2)NClNa,BusNClNa)对一系列环状烯丙基醇进行立体选择性叠氮化。这些反应的立体选择性高度依赖于烯丙基醇和氯胺盐的结构。通常,获得顺式和反式-羟基氮丙啶的混合物,其中主要的非对映异构体是顺式-羟基氮丙啶,而在1,3-二取代的烯丙基醇的叠氮化中观察到完全的顺式-非对映选择性。在每种研究的情况下,与使用TsNClNa进行相同反应所观察到的相比,使用BusNClNa进行叠氮化可以得到更高的顺式-立体选择性。出乎意料的是,将叠氮化条件应用于1-取代的环戊-2-烯-1-醇不会产生氮丙啶。反而,
