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-1β,3α-dihydroxy-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 1α,2α-epoxy-lup-3-one (9).The structures of the compounds have been established on the basis of analytical and spectral data.
