The structure determination of the title compound, rotenone alpha-oxime [systematic name: 1,2,12,12a-tetrahydro-8,9-dimethoxy-2-(1-methylethenyl)-[1]benzopyrano[3,4-b]furo[2,3-h][1]benzopyran-6(6H)-one oxime], C(23)H(23)NO(6), confirms that the molecule has an approximately V-shaped structure. One of the rings has a typical cyclohexene-like monoplanar conformation and the central ring adopts a 1,2-diplanar
标题化合物鱼藤酮α-肟的结构测定[系统名称:1,2,12,12a-四氢-8,9-二甲氧基-2-(1-甲基乙烯基)-[1]苯并吡喃[3,4-b ] furo [2,3-h] [1]苯并吡喃-6(6H)-一肟],C(23)H(23)NO(6)证实该分子具有近似V形的结构。其中一个环具有典型的类似环己烯的单平面构象,而中心环则采用1,2-双平面构象。
