The reaction of 2-(2′-chloroethoxy)-acetophenone (I) with non-hindered primary aliphatic amines is shown to give 4-alkyl-5-methylene-2.3.4.5-tetrahydro-1.4-benzoxazepines (IV) which can be smoothly hydrogenated to the corresponding 5-methyl derivatives VI. Steric limitations of this ring closure are discussed.
显示2-(2'-氯乙氧基)-苯乙酮(I)与无阻碍的伯脂族胺的反应产生4-烷基-5-亚甲基-2.3.4.5-四氢-1.4-苯并x氮平(IV),其可以是平稳氢化成相应的5-甲基衍生物VI。讨论了这种闭环的立体限制。
