Conditions for reduction of amino acids to amino alcohols without racemization are described for L-valine: Org. Synth. Coll., 7, 530 (1990).
Stable, convenient reagent for a wide range of reduction and hydroboration reactions. Reviews: Org. Prep. Proced. Int., 13, 225 (1981); Chem. Rev., 76, 773 (1976); A. Pelter et al, Borane Reagents, Academic Press, N.Y. (1988).
By use of refluxing THF as solvent, the reduction can be extended to include esters, primary, secondary and tertiary amides and nitriles: J. Org. Chem., 47, 1389 (1982); Synth. Commun., 21, 1579 (1991).
For a discussion of the effect of the alkene structure on hydroboration with borane dimethyl sulfide, see: J. Org. Chem., 48, 644 (1983). For cis-anti-Markovnikov hydration of alkenes by hydroboration with BMS, followed by H2O2 oxidation of the borane, see: J. Org. Chem., 39, 1437 (1974).
Carboxylic acids are readily reduced to alcohols: J. Org. Chem., 38, 2786 (1973).
The selectivity of BMS in reducing free acids more rapidly than esters is reversed in the case of monoesters of malonic acids. The borane binds initially to the acid function, but reduces the ester group intramolecularly: Tetrahedron Lett., 30, 6687 (1989):
