摘要：

The site-specific natural abundance deuterium distribution of hexanol (1) obtained through a variety of methods has been determined through H-2 NMR spectroscopy. This study, actually performed on the acetate ester 3, provides a means of distinguishing between ''natural'' materials isolated from natural sources or obtained by Colletotrichum gloeosporioides mediated reduction of natural hexanoic acid and other products of synthetic origin or produced from hexanoic acid by LiAlH4 reduction. Particularly significant were the variations of the molar fraction values at position 1 with respect to positions 3, 4, and 5.
