An efficient method for the selective synthesis of previously unknown α,ω-bis-1,5,3-dithiazepinanes based on the transamination reaction of N-tert-butyl-1,5,3-dithiazepinane and recyclization reaction of 1-oxa-3,6-dithiacycloheptane with aliphatic diamines in the presence of SmCl3·6H2O as the catalyst, has been developed.
对先前未知的α的选择性合成的有效方法,ω -双- 1,5,3-dithiazepinanes基于对氨基转移反应Ñ -叔丁基- 1,5,3-dithiazepinane和再成环反应1-氧杂已经开发了在SmCl 3 ·6H 2 O作为催化剂的情况下与脂肪族二胺形成的3,6-二硫代环庚烷。
