Asymmetric synthesis of mellein methyl ether: use of ortho-toluate carbanions generated by chiral bases

Abstract
An ortho-toluate carbanion generated from (2) by the chiral lithium amide base of (6), (7), or (11) undergoes an enantioselective aldol-type reaction with acetaldehyde to give mellein methyl ether (3), in up to 53% enantiometric excess.
