The subject invention provides a method of preparing an allylic amine having the structure: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are each independently hydrogen, halogen, cyano, nitro, linear or branched chain alkyl, aryl, etc.; wherein each alkyl or arylalkyl if present is independently unsubstituted or substituted by fluoro, cyano, nitro, linear or branched chain acyl, dialkylamino, etc.; wherein each aryl if present is independently unsubstituted or substituted by fluoro, cyano, nitro, linear or branched chain alkyl, arylmercapto, etc.; and wherein each of R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 optionally is covalently bonded linking pairwise a suitable atom from each to form from 0 to about 10 rings, wherein each ring contains between about four and about twelve atoms, using disubstituted sulfur diimides prepared in situ. Also provided are methods of preparing cyclic allylic amines in which allylic double bonds are endocyclic and exocyclic.
本发明提供了一种制备具有以下结构的
烯丙基胺的方法:##STR1## 其中R.sub.1,R.sub.2,R.sub.3,R.sub.4和R.sub.5各自独立地表示氢,卤素,
氰基,硝基,线性或支链烷基,芳基等;其中,如果存在烷基或芳基烷基,则每个烷基或芳基烷基独立地未取代或被
氟,
氰基,硝基,线性或支链酰基,二烷基
氨基等所取代;如果存在芳基,则每个芳基独立地未取代或被
氟,
氰基,硝基,线性或支链烷基,芳基
硫醇等所取代;并且R.sub.1,R.sub.2,R.sub.3,R.sub.4和R.sub.5中的每个都可以选择地以共价键连接成对,形成0至约10个环之间的环,其中每个环包含大约4至12个原子,使用原位制备的二取代
硫二
亚胺。还提供了制备环状
烯丙基胺的方法,其中烯丙基双键为内环和外环。
