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

Abstract
Improved procedure for the deracemization of a-methyl dihydrocinnamic aldehydes (2-methyl-3-phenylpropanals) with L-(þ)-tartaric acid salt of (S)-enantiomer of Betti’s base, is presented. The method enabled the transacetalization of N,O-ketal (R)-enantiomer of Betti’s base with various aldehydes.File in questo prodotto:
