Description

General description

Borane dimethyl sulfide complex (BMS) acts as a highly efficient and selective reducing agent in the presence of catalytic sodium tetrahydroborate for α-hydroxy esters. Asymmetric borane reduction of a variety of prochiral ketones with BMS using spiroborate esters as catalyst has been reported.

Application

Borane dimethyl sulfide complex (BMS) solution may be used in the following studies:

• One-pot conversion of alkynes into 1,2-diols.
• Preparation of iminopentitols.
• Reduction of representative organic functional groups, such as esters, nitriles and amides.
• Used along with a dendrimeric supported L-pyrrolidinol in the asymmetric reduction of indanones and tetralones.
• Asymmetric reduction of ferrocenyl-1,3-diketones to chiral 1,3-diols.
• Highly enantioselective reduction of ketones catalyzed by C₃-symmetric tripodal hydroxyamides.

Reactant used as a regioselective reducing agent

Reactant involved in:

• Hydroboration / oxidation
