8-2H2)tetradecanoic acids (threo-(7,8-2H2)-3) in Saccharomyces cerevisiae afforded 5,6-dihydroxy(5,6-2H2)dodecanoic acids (threo-(5,6-2H2)-4), which were converted to (5S,6S)-6-hydroxy(5,6-2H2)dodecano-5-lactone ((5S,6S)-(5,6-2H2)-7) with 80% e.e. and (5S,6S)-5-hydroxy(5,6-2H2)dodecano-6-lactone ((5S,6S)-5,6-2H2)-8). Further β-oxidation of threo-(5,6-2H2)-4 yielded 3,4-dihydroxy(3,4-2H2)decanoic acids (threo-(3
