Thionupharoline has been shown to be identical with 6-hydroxythiobinupharidine. The hydride reduction of hemiaminals of thiobinupharidine has been examined in ethanol solution. The steric course of reduction at C-6 is not nearly as selective as it ha

The sulfoxide configurations of neothiobinupharidine α- and β-sulfoxides have been determined through a 13C nmr investigation. The 13C nmr sulfoxidation increments (ΔδC-i = δC–iS–O − δC–iS) for all carbons in 2,2,4,4-tetramethylthiolane

The spectroscopic properties of thiobinupharidine and its isomer, neothiobinupharidine, of established structure, have been examined and compared. From this study it was possible to deduce the structure and relative configuration of the alkaloid. The

A new alkaloid, nupharolutine, (C15H23NO2) has been isolated from the basic extract of the rhizomes of Nupharluteum. By spectroscopic and chemical methods it is shown to be a hydroxy derivative of deoxynupharidine. The mass spectra of the new base an

A new alkaloid (C30H42N2O3S), isolated from Nupharluteum, is shown to be neothiobinupharidine sulfoxide. The mass spectra of neothiobinupharidine and the new alkaloid are discussed.
