摘要
Optically active 8-N,N-bis(ferrocenylmetllyl)aminomenthol 5. obtained by condensation of (-)-aminomenthol with ferrocenecarboxaldehyde followed by N-alkylation with (ferrocenylmethyl)trimethylammonium iodide and further reduction, was found to catalyze (5 mol%) the enantioselective ethylation of aromatic. aliphatic and organometallic aldehydes to secondary alcohols with high enantioselectivities (up to 95%) at room temperature.
