anabasine, 5,8,9,10,11,11a-hexahydro-6H-pyrido[2,1-f][1,6] naphthyridine (5), and related compounds are reported. Conformational assignments were made using NMR data (including coupling constants, homonuclear Overhauser effects, and 2D correlations) and the results of molecular mechanics (MM2) calculations. The tricyclic compounds have trans-quinolizidine ring fusion with a chair-shaped piperidine ring. The
“桥联”金刚烷,5,8,9,10,11,11a-六氢-6H-吡啶并[2,1-f] [1,6]萘啶(5)的合成和构象分析,是相关的化合物报告。使用NMR数据(包括耦合常数,同核Overhauser效应和2D相关性)和分子力学(MM2)计算结果进行构象分配。三环化合物具有与椅子形哌啶环的反式喹啉嗪环稠合。中心环显示标题化合物的半椅子构型,以及6-氧代衍生物的半船形。计算的邻位偶合常数与实验获得的相符。
