Asymmetric hydrogenation of 3-methyl-fumaric and maleic ester monoaldehydes protected as neph-derived oxazolidines

The hydrogenation of 3-methyl-fumaric and maleic ester mono aldehydes protected as oxazolidines of nor-ephedrine (NEPH) derivation has been studied. This transformation takes place with moderate to good π-face stereodifferentiation and allows the preparat
