2,3-Dihydro-2(R)-methyl-1,5-benzoxazepin-4(5H)-one E(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 converted into optically active 1,5-benzoxazepines (R)-7-(R)-14 and (S)-15-(S)-32.
