| dc.description | 8 pages, 2 tables, 2 schemes.-- Part X in the series ‘New Sources of Steroidal Sapogenins’. | - |
| dc.description.abstract | Four new steroidal sapogenins have been isolated from the leaves and twigs of Tamus edulis Lowe: 7-ketotamusgenin (IIIa), 7-ketodiosgenin (IVa), 25S-hydroxytamusgenin (Va) and afurigenin (IXa). Compounds IIIa, Va and IXa each bear a carbonyl group at C-11. The structures of IIIa and IVa have been confirmed by synthesis from tamusgenin and diosgenin, respectively, and that of Va by transformation into tamusgenin (Ia). For afurigenin, we provisionally propose structure IXa, based on its conversion into Va. | - |
