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.

    摘要: The large scale preparation of ethyl 2,2-difluoro-4- pentenoate and 2-fluorinated methyl aminoacetonitriles by reaction of 2-H-perfluoroethyl allyl ether and n-butyl lithium and fluoromethylacetonitrile and a Grignard reagent, respectively, is largly unsuccessful because of side reactions which convert intermediate products and reactants to undesired products. Applicants have overcome these problems by performing the reactions with cooling in a continuous manner in a flow reactor with short residence time.
