procedure, the functionalized 8-azabicyclo[3.2.1]octane 32, which is a potential intermediate for the syntheses of various tropane alkaloids, was prepared. Additionally, a new route for the construction of the bridged tetrahydro-beta-carboline ring system 5 has been developed that features the ring-closing metathesis of the enyne 45 to construct the bridging ring in 46. This concise route to 46 also features
已经开发了一种简便合成氮杂双环[mn1]烯烃(m = 3-5; n = 3,2)的新策略,该策略涉及顺式-2,6-二烯基-N的闭环易位(RCM)反应。 -酰基哌啶衍生物。从戊二酰亚胺(11)开始的六步中或从4-甲氧基吡啶(25)开始的三步中可以容易地制备必需的2,6-二烯基哌啶。在确定该方法实用性的一个实例中,制备了官能化的8-氮杂双环[3.2.1]辛烷32,其是合成各种托烷生物碱的潜在中间体。另外,已经开发出构建桥接的四氢-β-咔啉环系统5的新途径,其特征在于烯炔45的闭环易位以在46中构建桥环。到46的这种简明路线还具有潜在的通用性和有用的程序,用于从酯官能团一步制备末端炔烃。46中乙烯基的选择性氧化提供了不饱和醛47,其可以用作合成几种Sarpagine生物碱的有用中间体。

A facile and general entry to functionalized bridged bicyclic nitrogen heterocycles has been developed that involves the ring-closing metathesis (RCM) of cis-2,6-dialkenyl-N-acyl piperidines that were readily prepared from glutarimide or 4-methoxypyridine.
