Abstract: A method of increasing enantioselectivity in a reduction reaction of a prochiral substrate with a borane reagent including a borohydride species (for example, a borohydride stabilized borane-tetrahydrofuran complex) catalyzed by a chiral catalyst includes the step of maintaining the concentration of borohydride species in the borane reagent below approximately 0.005 M during the reduction of the prochiral substrate. A method of increasing enantioselectivity in a reduction reaction of a prochiral substrate with a borane reagent including a borohydride species that is catalyzed by a chiral catalyst includes the step of reducing the detrimental effect the borohydride species has on enantioselectivity by adding a Lewis acid. For example, the prochiral substrate can be a ketone and the chiral catalyst can be a chiral oxazaborolidine.

Abstract: A method for synthesizing an alkali-metal amide comprises the step of charging a reactor vessel with a reaction mixture comprising an alkali metal selected from the group of lithium, sodium, potassium or cesium, an electron carrier, and a disubstituted amine. The disubstituted amine preferably has the formula R1R2NH, wherein R1 and R2 are independently, the same or different, an alkyl group or —SiR3, wherein R3 is an alkyl group, an aryl group, or an aryl group substituted with an alkyl group. The reaction to form the alkali-metal amide product occurs without the use of a solvent.
