应用
二异丁基氢化铝溶液（1M；溶于THF中）是一种强力还原剂。它可用于以下反应：
- 合成经二肽保护的 反式-烯烃同构物。
- 原位生成双（1,5-环辛二烯）镍（0）（Ni（cod）2），其可催化将 乙烯基三丁基锡共轭加成至 2-丙烯醛，以形成 叔丁基二甲基[（（E）-1,4-戊二烯基）氧基]硅烷。
- 还原芳基丙酸酯，以得到相应的炔丙醇。
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。

The reaction of DIBALH with bis(heteroannulated)-pyranosides containing the perhydrofuro[2,3-b]pyran moiety is described. The hydride attack at the anomeric carbon (C-9a) resulted in the exclusive tetrahydrofuran ring opening. The selectivity of this reaction has been evaluated as other benzylidene acetals built

Reaction of purine nucleosides, such as 2',3'-isopropylideneinosine (1a) and 2',3'-isopropylideneadenosine (1c), with diisobutylaluminum hydride (DIBAL) in dry tetrahydrofurane resulted in the formation of the corresponding 9-(2',3'-isopropylideneribity)purines (2) in good yields. Oxidation of the ribityl derivatives (2) with NalO4 and subsequent

A systematic investigation of the reductive ring-expansion reaction of cyclic ketoximes fused to aromatic rings with diisobutylaluminum hydride (DIBALH) is described. This reaction regioselectively afforded a variety of five- to eight-membered bicyclic heterocycles or tricyclic heterocycles containing nitrogen neighboring an

An optimized protocol for the DIBALH reductive acetylation of acyclic esters and diesters is described. This reductive acetylation procedure allows a wide variety of esters to be converted into the corresponding alpha-acetoxy ethers in good to excellent yields. It was
