Article abstract of DOI:10.1007/BF00811547

2,3-Dihydro-2(R)-methyl-1,5-benzoxazepin-4(5H)-one <(R)-3> and its enantiomer (S)-3 have been synthesized via the optical resolution and subsequent chemical transformations of (+/-)-3-(2-nitrophenoxy)butyric acid (1).Compounds (R)-3 and (S)-3 were convert
