Abstract

(-)-N,O-diformylnorephedrine (-)-N-formylnorephedrine Catha edulis Celastraceae cisoid conformation formylation NMR transoid
The alkaloidal fraction of Catha edulis yielded upon repeated chromatography (-)-N-formylnorephedrine whose 1HNMR and 13CNMR spectra suggested the presence of cisoid (major) and transoid forms (minor). The identity of the isolated compound was established by comparison with the major product obtained by formylating (-)-norephedrine; the minor product was found to be (-)-N,O-diformylnorephedrine.
