研究了铜促进的各种烯烃底物的分子内氨氧化反应的非对映选择性。α-取代的4-戊烯基磺酰胺有利于形成2,5-顺式-吡咯烷(dr >20:1),产率在76-97%之间,而γ-取代的底物有利于2,3-反式吡咯烷加合物,具有中等选择性(ca. 3:1)。N-取代基直接连接到α-碳上的底物只能生成2,5-反式吡咯烷。该方法的合成效用通过(+)-monomorine的简短而有效的形式合成来证明。
The diastereoselectivity of the copper-promoted intramolecular aminooxygenation of various alkene substrates was investigated. α-Substituted 4-pentenyl sulfonamides favor the formation of 2,5-cis-pyrrolidines (dr >20:1) giving excellent yields which range from 76–97% while γ-substituted substrates favor the 2,3-trans pyrrolidine adducts with moderate selectivity (ca. 3:1). A substrate whose N-substituent was directly tethered to the α-carbon exclusively yielded the 2,5-trans pyrrolidine. The synthetic utility of the method was demonstrated by a short and efficient formal synthesis of (+)-monomorine.
