Products from the reaction of 11-dihomodriman-8α-ol-12-one with several reagents such as MeSO3SiMe3, CF3SO3SiMe3, Sc(CF3SO3)3, conc. H2SO4 in EtOH (30% solution), and Amberlist-15 ion-exchange resin were studied. 11-Dihomodrim-8(9)-en-12-one and its oxime were synthesized. The reaction of its oxime with H3PO4 (86%) or CF3CO2H produced (1S,2S,4aS,8aS)-2,5,5,8a-tetramethyldecahydro-1H-naphtho [1,2-e]-3-methyl-4,5-dihydro-[1,2,6]-oxazine; with p-TsCl in Py, (1S,2S,4aS,8aS)-2,5,5,8a-tetramethyldecahydro-1H-naphtho[1,2-d]-2-methylpyrroline-N-oxide; and with PCl5 in Et2O, 11-acetylaminodrim-8(9)-ene and 11-methylaminooxodrim-8(9)-ene.
