A series of derivatives of 2‐hydroxy‐3‐methylbut‐2‐ and ‐3‐enenitrile, including β‐D‐glucopyranosides, were obtained and their 1H and 13CNMR spectra were investigated. The spectra were assigned using lanthanide‐induced shifts, NOE difference spectroscopy and deuterium labelling.

was shown to be (2R)-2- (β- d -glucopyranosyloxy)-3-hydroxy-3-methylbutanenitrile by spectroscopic and chemical methods. The absolute configuration of this glucoside was correlated with that of proacacipetalin by oxymercuration of the latter, followed by borohydride reduction of the product.
摘要 从 Acacia sieberiana var. 的豆荚中分离得到一种新的氰苷。woodii,通过光谱和化学方法显示为 (2R)-2- (β-d-吡喃葡萄糖基氧基)-3-羟基-3-甲基丁腈。该葡糖苷的绝对构型与 proacacipetalin 的绝对构型相关,通过后者的氧汞化,然后是产物的硼氢化物还原。
