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.
研究了11-二氢二甲基-8α-醇-12-酮与几种试剂(如MeSO3SiMe3、CF3SO3SiMe3、Sc(CF3SO3)3、浓H2SO4在
乙醇(30%溶液)中的溶液以及Amberlist-15离子交换
树脂)的反应产物。合成了11-二氢二甲基-8(9)-烯-12-酮及其
肟。其
肟与H3PO4(86%)或CF3CO2H的反应产生了(1S,2S,4aS,8aS)-2,5,5,8a-四甲基十氢-1H-
萘并[1,2-e]-3-甲基-4,5-二氢-[1,2,6]-恶嗪;与Py中的p-TsCl反应产生了(1S,2S,4aS,8aS)-2,5,5,8a-四甲基十氢-1H-
萘并[1,2-d]-
2-甲基吡咯啉-N-氧化物;与Et2O中的PCl5反应产生了11-乙酰
氨基二甲基-8(9)-烯和11-甲基
氨基氧代二甲基-8(9)-烯。
