14-MethylC2, 3-3Hlhexadecanoic acid of a specific radioactivity of 5 1 Ci/mmol was pepared starting from 12-methyltetradecanoic acid isolated from wool fat. This fatty acid was converted into 12-methyltetradecanal which was reacted with ethyl diethylphosphonoacetate to yield 14-methylhexadecen-2-oic

✦ Synopsis
Methyl to-deuterated tetradecanoates have been prepared in high purity by two synthetic routes from methyl hydrogen tetradecanedioate. One method utilizes the selective reducing properties of sodium borodeuteride and sodium cyanoborodeuteride towards, acid chloride, ester, tosyloxy, and lode groups to introduce the deuterium label at only the carboxyl group of methyl hydrogen tetradecanedioate. The second procedure utilizes a coupling reaction between an organic halide and lithium di-(trideuteriomethyl) cuprate (I). Corresponding todeuterated derivatives of methyl hexadeeanoate may be prepared by the same methods from methyl hydrogen hexadecanedioate. The two methods should be generally applicable in the synthesis of to-deuterated alkanoie adds.
