The direct pyrrolidine-catalyzed α-sulfenylation of aldehydes and ketones with the commercially available, very cheap chemical tetramethylthiuram disulfide (thiram) is described. The dithiocarbamoyl derivatives are obtained in good to excellent yields (47-98%). In the case of α-substituted aldehydes the protocol allows the generation of quaternary stereocenters. The sensibility of the α-sulfenylated carbonyl compounds for racemization has been investigated.
