一般描述
二异丁基氢化铝还原剂通常用于将酯还原成醛。
应用
二异丁基氢化铝溶液（1.0M 己烷溶液）可用于合成二异丁基叔丁氧基铝氢化物（PDBBA），一种在硝基存在下将酯类化合物化学选择性转化的新型还原剂。DIBAL-三乙胺络合物可以将 α-羰基烯酮二硫代缩醛还原成饱和酮。
用于Pd催化的仲烷基溴的还原脱溴过程。过苄基化呋喃糖苷的O-脱苄基和开环。方便从 ZrCp2Cl2 和DIBAL-H原位生成 HZrCp2Cl。

A general method for the synthesis of enantiopure non-natural alpha-amino acids is described. The key intermediate tert-butyl (2S)-2-[bis(tert-butoxycarbonyl)amino]-5-oxopentanoate was obtained from l-glutamic acid after suitable protection and selective reduction of the gamma-methyl ester group by DIBALH.
