When (−)humulone is forced to absorb seven moles of hydrogen (catalytic hydrogenation), the principal product (40%) is 2,4-di-(3-methyl)butyl-6-(3-methyl)-butanoyl-resorcinol. This fact and other evidence indicates that the correct enol form of (−)humulone is II in Chart I. Interpretation of the ORD curve of (−)humulone in accordance with this enol structure, establishes that this natural substance
当(-))草酮被迫吸收七摩尔氢(催化氢化)时,主要产物(40%)是2,4-二-(3-甲基)丁基-6-(3-甲基)-丁酰基-间苯二酚。这一事实和其他证据表明,(-)mul草酮的正确烯醇形式为图I中的II。根据该烯醇结构对(-)mul草酮的ORD曲线进行解释,可以确定该天然物质具有R-构型和属于L系列。(-)四氢hydro草酮的臭氧化实验证实了这一结果。
