borabicyclo[3.3.1]nonane (Alpine-Borane). This is likely because of the extreme size disparity of groups on either side of the carbonyl. Here, we present a structure-reactivity study whereby the reductions of variably substituted d-benzaldehydes are explored using highly sensitive measures for enantiomeric excess and relative reactivity. These results are compared to the relativerates predicted from

This invention is directed to a method of performing a stereoselective reaction without use of a solvent comprising contacting a reactant with a chiral reagent under sonication conditions to form an excess of an enantiomer.
