摘要

氮杂卓化合物存在1H-

2H-

3H-和4H-共4个互变异构体

其中

2H-

3H-系统是最重要的。2H-氮杂卓母体化合物很不稳定

4位存在叔-丁基

并且环上含有丙硫基(PrS-)取代基的2H-氮杂卓

不仅发生H迁移

也能发生PrS-迁移

向较稳定的3H-氮杂卓异构化。以2

7-二甲氧基-4-甲基-2H-氮杂卓为原料

通过与Pr-SH的取代反应

合成7-甲氧基-4-甲基-2-PrS-2H-氮杂卓

并讨论分析产物的迁移反应。通过IR、

H NMR、

C NMR、MS检测表明

在室温条件下

4位存在甲基的2H-氮杂卓衍生物

选择性地发生 PrS-迁移

生成3H-氮杂卓

而且此异构化反应速度比叔-丁基存在时的情况更快。

Abstract

In many biologies and plants

the ring containing the nitrogen atom of azepine

which as biologically active substances

is an important group of organic compounds.There is tautomers between 1H-

2H-

3H- in azepine

among them 2H-

3H- system are the most important.2H-azepine is unstable index compound

through H migration

the 3H-azepine isomerization is relatively stable.The existence of four tert-butyl and PrS- ring substituent containing the 2H-azepine

it not only can migrate to hydrogen atom

but also the movement of sulfur occurred

and 3H-azepine isomerization occurs.Regarding 2

7-dimethoxy-4-methyl-2H-azepine as raw materials

through the substitution reaction with propyl thiol

7-methoxy-4-methyl-2-propylthio-2H-azepine was synthesized and migration reaction was analyzed.IR

H NMR

C NMR

MS obervation showed that

at room temperature

the seletive PrS-migration base on 2H-azepine ring with 4-methyl 2H-azepine occures and 3H-arepine is established

wiche is faster than that with exitstence of tert-butyl.
