An efficient synthetic procedure is described for the preparation of 4- and 5-oxocarboxylic acids by reaction of the corresponding lactones with commercial bleach.

Optically active 4-alkyl-γ-butyrolactones and 5-alkyl-6-valerolactones were obtained in high enantiomeric excesses (85-95percent e.e.) from the catalytic asymmetric alkylation of 3- and 4-formylesters with dialkylzincs using N,N-dibutylnorephedrine as catalyst.

Racemic lactones were optically activated through the hydrolysis with sodium hydroxide followed by the partial neutralisation with (1S)-(+)-10-camphorsulfonic acid in ethanol to afford R- or S-isomer with 99 - 38percent ee.
