Kineticresolution of α-furfuryl amide was first carried out by using the modified Sharpless asymmetric epoxidation reagent to give the slow-reacting enantiomers, (S)-1a–h and (R)-1b,f in high enantioselectivity(90–100% e.e) and high chemical yield (45–50%). Similar results were obtained from the fast-reacting enantiomers. This kineticresolution exhibits the reversed enantioselectivity.
