An inversion mechanism had been previously observed in the hydroxylation of caranine (2) to lycorine by Wildman and Heimer. They observed 7% incorporation of [2/ -3H] caranine into lycorine in Zephyranthes Candida Herb., the 3H being retained at C-2 of 1 as shown by the conversion into the inactive 385. The stereospecifically labeled precursor was obtained through LiAl3H4 reduction of lycorine-1,2-a-epoxide prepared from lycorine via its cis-chlorohydrin and chromatography on Florisil. The structure of the a-epoxide rests on physical and chemical grounds, whereas the stereochemistry of the... [Pg.148]

Further investigations of the flowers of Amaryllidaceae species has revealed several new alkaloidal phospholipids, 2-O-glycerophosphoryllyco-rine (30), phosphatidyllycorine (31-34), phosphatidyllycorinium metho-cations (35), and phosphatidylpseudolycorine (36-39), respectively, in an extract of the flowers of Zephyranthes flava 107) (Fig. 7). The structures of the alkaloids were established by comprehensive spectroscopic analyses... [Pg.342]

Tazettine (298) has been isolated from Crinum americanum (leaves) (76), C. giganteum (27), Hippeastrum equestre (bulbs) (40), Hippeastrum hybrids (bulbs) (42), Hymenocallis expansa (bulbs and leaves) (48), Lycoris radiata (bulbs) (60), Narcissus tazetta (90), N. cantaricus (whole plants) (65), Pancratium maritinum (bulbs) (96), and Stembergia sicula (whole plants) (103). Pretazettine (300) has been found in N. pallidiflorus (whole plants) (76), N. panizzianus (whole plants) (79) (aerial and bulbs) (80), S. culsiani (bulbs) (102), and Zephyranthes flava (fresh mature seeds) (70S). Tazettine (298), pretazettine (300), littoraline (301), and marconine (302) have been isolated... [Pg.387]

Nerinine was isolated from Nerine samiensis and shown to possess the empirical formula C19H25NO5 (70). Analysis of the alkaloid showed the presence of three methoxyls and one N-methyl group. Subsequently, nerinine was isolated from Zephyranthes Candida by Boit and Ehmke... [Pg.336]

Zephyranthine (mp 201°-202° [ajj, —43.2° in CHCI3) was isolated from Zephyranthes Candida. It forms a picrate (mp 194°-195°) and a methiodide (mp 294°-295° decomp.). It is stable to catal3dic hydrogenation but forms an 0,0-diacetate and an isopropylidene derivative. The alkaloid is identical with a-dihydro-2-epilycorine (XIV R = OH) (63). [Pg.334]

The bulbs of Hippeastrum ananuca have been shown to contain lycorine, homolycorine, and the rare alkaloid maritidine (1). Lycorine has also been isolated for the first time from the rhizomes of Curculigo orchioides and from the leaves of Ungernia tadshicorum maritidine is a constituent of Zephyranthes robusta and of Z. sulphurea and an X-ray crystallographic study of the alkaloid has been carried out. Two new alkaloids, hippeastidine (2) and 17-epi-homolycorine (3), were obtained from Hippeastrum ananuca and their structures were established by X-ray analysis. [Pg.135]
