The highly functionalized organofluorine compounds 3a-c were prepared from the activated dichlorinated sulfides 2a-c by displacement of a chlorine atom using nucleophilic fluorination agents such as dihydrogenfluoride polymer-supported. Fluorination of sulfoxides 5a-c with diethylaminosulfur trifluoride gives monofluoro sulfides 6a-c, subsequently transformed into α-chloro-α-fluoro sulfides 3a-c and
Enzymatic hydrolyses of the σ-symmetric dicarboxylic diesters bearing a sulfinyl group as the prochiral center were examined by employing porcine liver esterase and procine pancreatic lipase. Eventually, their chiral half esters were elaborately obtained as the corresponding chiral phenacyl esters. The stereochemistry of the chiral half esters was determined by the X-ray analysis and their chemical correlations.
