directly by the oxidation of the corresponding serine derivative 1 with dimethylsulfoxide which is activated by p-toluenesulfonyl chloride. The enol tosylate 3 retains reactivities characteristic of aldehydes like those expected for the corresponding dehydroserine derivative 2. A typical reaction of 3 includes substitution of the tosyl group with nucleophiles such as primary and secondary amines, leading
