  A spirofluorenol such as 3′,9′-dimethoxy-5′-hydroxyspiro[(1H-cyclopent[d,e,f]phenanthrene)-1,7′-benzo [c] fluorene] is produced by protecting a hydroxyl group bonded to a particular fluorenone compound such as 3,9-dimethoxy-5-hydroxybenzo[c]fluorene-7-one with “a substituted silyl group in which the sum of carbon atoms of substituents bonded to a silicon atom is 5 to 12”, such as a t-butyldimethylsilyl group, then, reacting the fluorenone compound with a particular organometal compound such as 1-lithiophenanthrene so as to be transformed into a spiro form and, then, removing the protection therefrom. This method makes it possible to efficiently produce the spirofluorenol which is useful as a starting material for producing photochromic compounds.

  通过保护与特定芴酮化合物（如3,9-二甲氧基-5-羟基苯并[c]芴-7-酮）相连的羟基，使用“取代硅基团，其中硅原子上的取代基的碳原子总数为5至12”，例如t-丁基二甲基硅基团，制备出螺旋芴醇，例如3′，9′-二甲氧基-5′-羟基螺旋[(1H-环戊[d，e，f]菲-1,7′-苯并[c]芴)]。然后，将芴酮化合物与特定的有机金属化合物（如1-锂菲）反应，使其转化为螺旋形式，然后去除保护。该方法可以有效地生产螺旋芴醇，该物质可用作生产光致变色化合物的起始材料。
