Synthesis of α-Arylthioalkyl Esters: The Addition Reactions of Vinyl Esters with Arylthiols Catalyzed by Lipase

α-Arylthioalkyl esters can be prepared by the addition reactions of vinyl esters with arylthiols in the presence of Pseudomonas lipase (PSL) as catalyst. In the toluene, the reaction mixtures were stirred at 60 °C for three days, the chemical yields up to 85% were obtained.
