The osmium-catalyzed oxidative cyclization of amino alcohol initiators formally derived from 1,4-dienes is an effective method for the construction of pyrrolidines, utilizing a novel reoxidant (4-nitropyridine N-oxide = NPNO). The cyclization of enantiopure syn- and anti-amino alcohols gives rise to enantiopure cis- and trans-2,5-disubstituted pyrrolidines, respectively. Moreover, the cyclization of
形式上衍生自1,4-二烯的氨基醇引发剂的os催化氧化环化是一种利用新型再氧化剂(4-硝基吡啶N-氧化物= NPNO)构建吡咯烷的有效方法。对映体纯的顺式和反式氨基醇的环化分别产生对映体纯的顺式和反式-2,5-二取代的吡咯烷。此外,显示带有环外螯合基团的双-均烯丙基胺的环化是反式-吡咯烷形成的补充方法。
