一般描述

Lithium dimethylaminoborohydride is a reagent exhibiting dual properties like a metal hydride and nitrogen nucleophile. It is generally considered as an alternative to lithium aluminum hydride (LAH) for the reduction of carbonyl compounds, amides, and lactams.

应用

在与卤代吡啶和伯烷基甲磺酸酯反应的情况下，LAB 可以转移胺部分。

能够还原各种官能团。

Lithium aminoborohydride (LAB) reagents initiate the amination or reduction of alkyl methanesulfonate esters, as dictated by reaction conditions. Alkyl methanesulfonate esters treated with unhindered LABs provide tertiary amines in excellent yield. Reduction to the corresponding alkane is achieved using a
