Improved procedure for the deracemization of alpha-methyl dihydrocinnamic aldehydes (2-methyl-3-phenylpropanals) with L-(+)-tartaric acid salt of (S)-enantiomer of Betti%26apos;s base, is presented. The method enabled the transacetalization of N,O-ketal (R)-enantiomer of Betti%26apos;s base with various aldehydes.
