accessed; the benzhydryl group confers high diastereocontrol for derivatising the six-membered ring, allowing access to 2,5,6-trisubstituted piperidines, and to 2,6-disubstituted piperidines such as pinidine.
亚胺博士2 CHNCHCO 2的Et,从二苯甲基胺和乙醛酸乙酯生成,提供了一种狄尔斯-阿尔德加合物与1,3-戊二烯从中范围的顺式-2,6-二取代的哌啶可以访问; 苯甲基使六元环衍生化具有较高的非对映异构控制性,从而可与2,5,6-三取代的哌啶和2,6-二取代的哌啶(例如吡啶)接触。
