Oxazepines and thiazepines, XX: CD-spectra of optically active 2-phenyl-2,3-dihydro-1,5-benzothiazepin-4(5 H)-ones and related 3-phenylthio-3-phenyl-propionic acid derivatives, and X-ray diffraction of one phenylethylamide

The absolute configuration of (-)-(1′R,3 S)-4 has been determined by X-ray diffraction. The UV- and CD-spectra of the title compound 8 and the intermediates for its synthesis are discussed. The stronger Cotton effects can be explained by application of the exciton theory to the observed CD-couplets. The CD of the lower homologue 9 of known absolute configuration is in full agreement with that of homochirally analogue 8.
