A straightforward and practical approach was established for the synthesis of nicotine and anabasine analogues by the cyclization of mesylated 1‐(3‐pyridinyl)‐1,4, and 1,5‐diol derivatives to form the pyrrolidino or piperidino fragments. Nicotine analogue (S)‐15 was prepared with good enantioselectivity using the developed azacyclization procedure of nonracemic (R)‐1‐pyridin‐3‐yl‐butane‐1,4‐diol, which
通过将甲磺酰化 1-(3-吡啶基)-1,4 和 1,5-二醇衍生物环化形成吡咯烷基或哌啶基片段,建立了一种直接而实用的合成尼古丁和 anabasine 类似物的方法。尼古丁类似物 ( S ) -15使用先进的非外消旋( R )-1-吡啶-3-基-丁烷-1,4-二醇的氮杂环化方法制备,具有良好的对映选择性,该方法是通过硼烷介导的酮还原获得的12在衍生自二苯基脯氨醇和乙二醇的螺硼酸酯存在下。J. 杂环化学,(2009 年)。
