R-(+)- and S-(−)-α-phenylethylamine yielded diastereomeric salts (+29 and −29) whose crystallization and subsequent esterification resulted in optically active acyclic amines (−13 and +13) with the asymmetric center only at the N atom in the open chain.
具有叔N-烷基取代基的烷氧基胺被氯化成N-氯-N-烷氧基胺,其与醇的反应使得能够合成N,N-二烷氧基胺。使用DNMR方法确定这些化合物的转化障碍。碱性水解(13),随后与R -(+)-和S -(-)-α-苯乙胺反应,生成非对映异构盐(+ 29和-29),其结晶和随后的酯化反应产生旋光性无环胺(− 13)和+ 13),其不对称中心仅在开链的N原子上。
