Stereochemical control in the preparation of 2-substituted1,2,3,4,6,7,12,12b-octahydroindolo[2,3-]quinolizinespossessing at will the C(12b)H-C(2)H cis or trans configuration was achieved by catalytic reduction of the 2,3-dehydro analoques,which were either unsubstituted on the indole nitrogen orsubstituted with a BOC-group, respectively. The contribution ofdifferent conformations to the conformational
立体化学控制制备2-取代的1,2,3,4,6,7,12,12b-八氢吲哚[2,3- ]喹啉具有随意的C(12b)HC(2)H顺式或反式构型通过催化还原2,3-脱氢类似物,它们分别在吲哚氮上未被取代或被BOC-基团取代。通过13 C NMR光谱分析估计不同构象对所制备化合物的构象平衡的贡献。
