[reaction: see text] Stereocontrolled synthesis of 2,4,6-trisubstituted piperidine diastereomers has been realized from common intermediates, obtained by a one-pot azaelectrocyclization protocol. Based on the method, the asymmetric synthesis of an indolizidine alkaloid, (-)-dendroprimine, was achieved.
[反应:见正文]由一锅氮杂电环化方案获得的常见中间体已经实现了2,4,6-三取代哌啶非对映异构体的立体控制合成。基于该方法,实现了吲哚并立定生物碱(-)-dendroprimine的不对称合成。
