From enantiomeric (R)-(-)- and (S)-(+)-2-methylbutyl bromide (3), available by resolution of (R)-(-)-phenylglycinol amides of rac-2-methylbutanoic acid, and from enantiomeric 6-methyloctyl bromide (7) the corresponding phosphonium salts were obtained.Wittig olefination yielded the optically active methyl-branched olefinic THP ethers 12 and 13, hydrolysis, catalytic hydrogenation, and acetylation gave rise to the formation of the chiral title compounds (R)-(-)- and (S)-(+)-10-methyldodecyl acetate (1) and (R)-(-)- and (S)-(+)-12-methyltetradecyl acetate (2).
