Fluorinated alkenylamines of the Formula V ##STR1## wherein n represents 0, 1, 2 or 3; R.sub.1 represents hydrogen or C.sub.1 -C.sub.10 alkyl and Y represents (a), when n represents O, CH.sub.2 F, (b), when n represents 1, CH.sub.2 F or CHF.sub.2, or (c) when n represents 2 or 3, CH.sub.2 F, CHF.sub.2 or CF.sub.3 are novel process intermediates. They are obtained by hydrolysis and subsequent reduction of the corresponding alkenyl fluorinated methyl ketimine magnesium halides, which are novel compounds resulting from reaction of the corresponding alkenyl magnesium halides with the corresponding fluorinated acetonitriles. The fluorinated alkenylamines of Formula V are oxidized while the amino group is protected to provide, after removal of the amine protecting group, the corresponding fluorinated methyl aminoalkanoic acids which are useful pharmacological or anti-bacterial agents.
化学式V的氟化烯基胺,其中n表示0、1、2或3;R.sub.1表示氢或C.sub.1 -C.sub.10烷基,Y表示(a),当n表示O时,CH.sub.2 F,(b),当n表示1时,CH.sub.2 F或CHF.sub.2,或(c)当n表示2或3时,CH.sub.2 F,CHF.sub.2或CF.sub.3是新型的过程中间体。它们是通过水解和随后还原相应的烯基氟化甲基酮亚胺镁卤化物获得的,这些化合物是由相应的烯基镁卤化物与相应的氟化乙腈反应而得到的。化学式V的氟化烯基胺在保护氨基的同时被氧化,以提供在去除胺保护基后得到的相应的氟化甲基氨基烷酸,这些酸是有用的药理学或抗菌剂。
