Abstract

Oximes of α-keto esters are reduced to obtain the corresponding amino alcohols using NaBH4 in combination with I2, CH3COOH, TiCl4, ZrCl4, COCl2, H2SO4, and TMS-Cl in 60-85% yields. The racemic phenylglycinol, phenylalaninol, and 2-aminobutanol are resolved using dibenzoyl-l-tartaric acid to obtain enantio­meric samples of >98% ee.
