5) Rationalizing the stereochemical outc ome of this reaction requires an understanding of the f borohydride borohydride lcohol. An three-dimensional structure of benzoin and the general reaction mechanism o reductions. As shown previously (10-1), the usual mode of activation tor reduction occurs via an intermolecular H-bond between the carbonyl group and an a intramolecular H-bond can stabilize the lowest-energy conformation of benzoin (pre and serve to activate the carbonyl for reduction, thus generating the lowest-energyt state. a) Draw the lowest-energy,...
