Benzyl Alcohols

The synthesis of optically active α-alkoxymethyl benzyl alcohols by reaction of polysubstituted benzaldehydes with chiral α-alkoxymethyllithiums, easily obtained by transmetallation of the corresponding α-alkoxystannanes with n-butyllithium, is reported. Chemical yields of the transformation are good while low asymmetric induction (<1.6:1) is obtained. Key words: diastereoselective synthesis, monoprotected glycols, chiral alkoxymethyllithiums, addition to aldehydes, optically active alcohols.
