The Uses of L-Selectride

Lithium triisobutylhydroborate is used as a reducing agent. Reagent for: Enantioselective synthesis of a-amino acids via reduction of N-tert-butanesulfinyl ketimine esters. Diastereoselective reduction reactions. Hydride reduction of the Danishefsky pyranones. Asymmetric reductive aldol reaction of enones with a-alkoxy aldehydes. Synthesis of alkanols by carbonylation reactions.

The Uses of L-Selectride

L-Selectride Solution is a reducing agent which is used in the preparation of oxygen heterocycles. Used also as a reactant in the synthesis of novel bicicyclo[3.1.0]hexane analags which may prove useful in the treatment of depression.
