摘要
A practically simple three-component chiral derivatization protocol for determining the enantiopurity of chiral hydroxylamines by H-1 NMR spectroscopic analysis is described, involving their treatment with 2-formylphenylboronic acid and enantiopure BINOL to afford a mixture of diastereomeric nitrono-boronate esters whose ratio is an accurate reflection of the enantiopurity of the parent hydroxylamine.
