The stereochemistry of castor stearoyl-ACP Î9 desaturase-mediated 10-sulfoxidation has been determined. This was accomplished by 19F NMR analysis of a fluorine-tagged product, 18-fluoro-10-thiastearoyl ACP S-oxide, in combination with a chiral solvating agent, (R)-AMA. Sulfoxidation proceeds with the same stereoselectivity as hydrogen removal from the parent stearoyl substrate. These data validate the use of thia probes to determine the stereochemistry and cryptoregiochemistry of desaturase-mediated oxidations.

the α oxidation of saturated, unsaturated, and heteroatom-containing (oxygen, sulfur) carboxylic acids 1 by the enzyme extract of peas (Pisum sativum) indicate that this biotransformation proceeds highly enantioselectively. For the first time, the synthesis of optically pure 2-hydroxy acids 2 has been achieved on the semipreparative scale (1 mmol) by α hydroxylation of long-chain carboxylic acids with
