The chiral cyclic sulfur-containing oxazaborolidine catalyst reacts with aromatic ketone in the presence of borane to form the catalyst-alkoxyborane adduct with a B-O-B-N four-membered ring. The ab initio molecular orbital method is employed to study the structures of the catalyst-alkoxyborane adduc

In the present paper, the ab initio molecular orbital method is employed to study the structures of the adducts of borane and aromatic ketone to chiral cyclic sulfur-containing oxazaborolidine used as a catalyst in the enantioselective reduction of aromatic ketone. The catalyst-borane-ketone adducts
The ab initio molecular orbital method is employed to study the structures and properties of chiral cyclic sulfur-containing oxazaborolidine, as a catalyst, and its borane adducts. All the structures are optimized completely by means of the Hartree-Fock method at 6-31g \* basis sets. The catalyst is
