A New Approach to the Synthesis ofN-Arylakyl Aminoalcohols
摘要:
N-arylmethyl substituted aminoalcohols were prepared by enantioseletive reductive amination of different aromatic and heteroaromatic aldehydes using aminoalcohols and NaBH3CN as a catalyst. The reaction of optically active aminoalcohols afforded optically pure products.

Naproxene ((+)-6-methoxy-.alpha.-methyl-2-naphthaleneacetic acid) is recovered from the corresponding racemic acid by treatment of the latter with N-substituted R-(-)-2-amino-1-butanols and recovery of the resulting diastereomeric salt.
