A series of 18-fluoro thiastearates were prepared and incubated with a yeast Δ9-desaturating system. The relative efficiency of desaturase-mediated sulfoxidation was monitored via19F-NMR analysis of the sulfoxide products, and a strong preference for oxo transfer to the S-atom occupying the 9-position was confirmed. The oxidation profile obtained in this manner matched that of analogous experiments
