Oxazepines and thiazepines. XIII—conformational analysis of 2,3-dihydrobenzothiazepine derivatives
摘要:
AbstractThe conformation and relative configuration of various condensed heterocycles possessing a 2,3‐dihydro‐1,5‐benzothiazepine moiety and their synthetic intermediates were determined by 1H and 13C NMR spectroscopy. It was found that epimerization takes place during the ring closure reaction.
