A 1:1 mixture of (1)AuCl [1 = P(t-Bu)2o-biphenyl] and AgSbF6 catalyzes the intramolecular amination of allylic alcohols with alkylamines to form substituted pyrrolidine and piperidine derivatives. Gold(I)-catalyzed cyclization of (R,Z)-8-(N-benzylamino)-3-octen-2-ol (96% ee, 95% de) led to isolation of (R,E)-1-benzyl-2-(1-propenyl)piperidine in 99% yield with 96% ee, consistent with the net syn addition
( 1 )AuCl [ 1 = P( t- Bu) 2 o-联苯]和AgSbF 6的1:1混合物催化烯丙醇与烷基胺的分子内胺化,形成取代的吡咯烷和哌啶衍生物。金 (I) 催化 ( R,Z )-8-( N -苄氨基)-3-辛烯-2-醇 (96% ee, 95% de) 环化导致分离 ( R,E )-1-苄基-2-(1-丙烯基)哌啶的产率为 99%,ee 率为 96%,这与胺相对于离开的羟基的净顺式加成一致。
