烟碱化合物的固相合成研究

Study on solid-synthesis of nicotine compounds

  • 摘要: 开发了一种高效的烟碱化合物的固相合成新方法. 利用交联聚苯乙烯负载磺酸树脂,经树脂氯化,制备出聚苯乙烯负载磺酰氯树脂作为固载有机硫试剂. 从3-溴吡啶出发,经锂化酰化、羰基还原、羟基磺酰化、磺酸酯胺化环化4步反应,合成了5个烟碱类化合物,总产率为52%~66%,产物结构经1H NMR鉴定确认. 方法具有产率高、操作简单,树脂可以回收再用,具有工业自动化生产的应用前景等特点.

     

    Abstract: In this paper, a new method for the efficient solid-phase synthesis of nicotine compounds has been developed. A polystyrene-supported sulfonyl chloride resin was prepared from cross-linked polystyrene-supported sulfonic acid resin as a solid-phase organosulfur reagent. Starting from 3-bromopyridine, five nicotine compounds were synthesized by four-step reactions including lithiation/acylation of pyridine, reduction of carbonyl group, sulfonylation of hydroxyl group, and amination/cyclization of sulfonate with overall isolated yields of 52%−66%, and the structures of the synthesized nicotine compounds were identified by 1H NMR. The method features high yields, simple operation, recycling and reuse of the resin, and the prospect of application in industrial automation production.
