| Lithium triisobutylhydroborate Usage And Synthesis |
| Description | Lithium tri-sec-butylborohydride, commercially available as a one molar solution in tetrahydrofuran. It is widely used as a mild and strong reducing agent with high stereoselectivity in organic synthesis. |
| Features | Lithium tri-sec-butylborohydride is a new type of hydride reducing agent, which has the characteristics of strong reducing ability and high regio- and stereoselectivity. |
| Preparation | Lithium triisobutylhydroborate can be prepared by:In a 3000ml three-necked flask, add 1000ml of 1mol/L tri-sec-butylboron tetrahydrofuran solution, add 1000ml of 1mol/L triethylenediamine tetrahydrofuran solution simultaneously, introduce nitrogen to start stirring, put the mixture of the two in an ice-water bath After cooling to 0° C., 1000 ml of a 1 mol/L lithium aluminum hydride solution in tetrahydrofuran was slowly added dropwise to the above mixed solution with a constant pressure funnel for about 10 hours. |
| Physical properties | clear colourless solution |
| Uses | 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. |
| Uses | 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. |
