Secodihydrocastoramine (11) was isolated from Nuphar japonicum (29, 30). The structure was determined by IR and H-NMR measurements. The hydrochloride of 11 on treatment with phosphorus tribromide produced an epimer of deoxycastoramine. [Pg.223]

Alkaloids were first detected in these plants by Dragendorff (J), who found them in 1879 in the rhizome of N. luteum. Soon thereafter Griining 2) isolated nupharine, an amorphous alkaloid to which he ascribed the formula C18H24O2N2. Not until 40 years later did Arima and Takahashi (3) obtain from Nuphar japonicum another alkaloid, which had the formula C15H23O2N and which they named nupharidine. In 1943 Kotake et al. isolated another alkaloid, deoxynupharidine, C15H23ON. [Pg.441]

The rhizomes of Nuphar japonicum and N. luteum (Nymphaeaceae) contain sesquiterpene-derived alkaloids that possess a quinolizidine nucleus (Howard and Michael, 1986). These compounds are based on a C15 skeleton of which part has been elaborated into a 3-substituted furan (Howard and Michael, 1986) (Fig. 36.4). [Pg.670]

Nuphar japonicum is a rhizobium herb used in folk medicine as diuretics and stomach analgesics, mainly in China and Japan. The ring opening of aziridine 286 followed by alkylative cyclization with allyl acetate 287 in the presence of a Pd-catalyst afforded piperidine 288. It was the effective starting material to synthesize alkaloids 289 (Scheme 40.64). [Pg.1239]
