Reduction of the ester group in the Baylis-Hillman adducts by NaBH 4 reduction is facilitated by the secondary hydroxyl group present at their β-position. This method is efficient for the preparation of substituted propane-1,3-diols.

The two enantiomers of Iopanoic acid 1 were prepared in enantiomeric excess higher than 90percent by enzyme-catalyzed hydrolysis of precursors (+/-)-2a and (+/-)-3a, followed by standard chemical transformations.Among the tested enzymes, chymotrypsin and Lipase PS proved to be the most selective catalysts.The stereochemical outcome of the lipase-catalyzed hydrolyses of esters (+/-)-2a-d is strictly dependent upon both the size of the alkyl group attached to the chiral center and the substituent in the aromatic ring.The enantioselectivity of the reactions was evaluated by chiral HPLC and the configurations of the new products were assigned by chemical correlations.
