This paper describes a concise and practical route to enantiomerically enriched 5‐alkyl substituted nicotine analogs. The Vilsmeier reaction was used to construct the nicotinaldehydes ring followed by the introduction of the chiral homoallylic alcohol by organic boron reagent and the cyclization of the pyrrolidine ring through the reduction of a chiral azide. 17 analogs have been synthesized and their
本文描述了一种简便,实用的方法,以对映体形式富集5-烷基取代的烟碱类似物。使用Vilsmeier反应来构建烟醛醛环,随后通过有机硼试剂引入手性均烯丙基醇,并通过手性叠氮化物的还原使吡咯烷环环化。合成了17个类似物并测试了其相应的生物学活性,其中化合物10d和10g对RD和SY-SY5Y表现出优异的IC 50值。
