摘要：

A practically simple three-component chiral derivatization protocol for determining the enantiopurity of chiral 1,2-, 1,3-, and 1,4-diols by H-1 NMR spectroscopic analysis is described. The method involves treatment with 2-formylphenylboronic acid and enantiopure alpha-methylbenzylamine to afford a mixture of diastereolsomeric iminoboronate esters whose ratio is an accurate reflection of the enantiopurity of the parent diol.
