2‐Propyl‐2‐pentenoic acid was prepared. Its stereochemistry was determined using the A.S.I.S.‐effect. The dehalogenation by N,N‐diethylaniline of some N‐substituted 2‐bromo‐2,2‐dipropyl‐acetamides gave the corresponding unsaturated amides. The configurations of these compounds are discussed on the basis of NMR data obtained with and without complexation with tris(dipivaloylmethano)europium [Eu (DPM)3]
制备2-丙基-2-戊烯酸。使用 ASIS 效应确定其立体化学。一些N-取代的2-溴-2,2-二丙基-乙酰胺经N,N-二乙基苯胺脱卤得到相应的不饱和酰胺。这些化合物的构型是根据与三(二新戊酰基甲烷)铕[Eu (DPM) 3] 络合和未络合而获得的 NMR 数据进行讨论的。
