The differential oxidation of five and six-membered endocyclic enecarbamates was investigated employing m-CPBA, DMD, as well as enantioselectivc protocols such as the Kochi-Jacobsen-Katsuki's epoxidation and the Sharpless dihydroxylation. By this strategy the syntheses of β- hydroxyprolines and β-hydroxypipecolic acids were accomplished, X-Ray crystallographic analysis of the trans-β-hydroxypipecolic acid was instrumental to solve structural assignment conflicts.
