Davis, Franklin A.; Kumar, Anil published the artcile< Kinetic resolution in the asymmetric hydroxylation of enolates. Stereospecific synthesis of (2S,3R)-(-)-verrucarinolactone>, Recommanded Product: (4aS,7R,8aS)-9,9-Dimethyltetrahydro-4H-4a,7-methanobenzo[c][1,2]oxazireno[2,3-b]isothiazole 3,3-dioxide, the main research area is methylvalerolactone asym hydroxylation camphorylsulfonyloxaziridine; verrucarinolactone stereoselective preparation.
Asym. hydroxylation of (±)-3-methylvalerolactone (I; R = H) with substoichiometric amounts of the (-)-(camphorylsulfonyl)oxaziridine affords (2S,3R)-(-)-verrucarinolactone (I; R = HO) in 60% ee, which on crystallization is obtained enantiomerically pure. This result not only represents a highly efficient stereospecific synthesis of an important lactone, but also demonstrates the application of kinetic resolution and asym. hydroxylation in the synthesis of enantiomerically enriched α-hydroxy carbonyl compounds having multiple stereocenters.
