An efficient metal-free method for the synthesis of alpha-ketothioesters is described for the first time. This reaction features the ability of pyrrolidine to fine-tune the reaction between 2-oxoaldehyde and thiols through iminium to the desired product in moderate to!:good yields. As an advantage, no external oxidants Or metal catalysts are required in our method: Reactions performed under modified conditions lead to an apparent balance in reactivity of secondary amine and thiols toward 2-oxoaldehydes.
