摘要：

Lupanone (1) on prolonged heating with selenium dioxide in t-butanol furnishes six products, lup-1-en-3-one (2), lup-1(2)-en-3-one-2-selenide (3), lup-1(2)-en-3-one-2-bis-selenide (4), 3-carboxy-1-beta, 3 adihydroxy-A-norlupane (5), A-norlupan anhydride (6), 1-hydroxylupan anhydride (7) and 1-hydroxy-A-norlup-2-carb -->4-olide (8). Oxidation of 3/4 with alkaline H2O2 affords 1 alpha,2alpha-epoxy-lup-3-one (9). The structures of the compounds have been established on the basis of analytical and spectral data.
