13-Oxobaccatin III (4) was oxidized to 7,13-dioxo D-secobaccatin III (5). This compound, when treated with base or cyanide ion, underwent rearrangements involving the rupture of the C-7,C-8 bond, the migration of the benzoyl and acetyl groups and intramolecular formation of new rings. Four new compo

Abstraef. Treatmem of 7-triethylsilyl-13-oxobaccatin III (1) with sodium hydride and methyl iodide gave the methylated ten-membered rin~ compound 2 that rearranged, via intramolecular aldol eundensation, to unsaturated decalin ring system (3, 4,5 ). These molecules were characterized by ID
