This is the wonderful reduction reagent compared to Red-Al. Dicarboxylic ester can be reduced to mono-OH. it is especially used for the lactone reduction to alcohol. the condition is mild, the reduction is so efficient and clean. the best thing is that it tolerate many functional group like halogen and ester. I also think it is mild lewis base.
