An adamantanemethanol derivative of the invention is represented by the following formula (1), wherein Ra is a hydrogen atom or a hydrocarbon group; Rb is a hydrocarbon group having a carbon atom, to which carbon atom at least one hydrogen atom is bonded, at a bonding site with the adjacent carbon atom; Rc, Rd and Re are each a hydrogen atom, a hydroxyl group which may be protected by a protective group or the like; provided that a hydroxyl group protected by a protective group or the like is bonded to at least one carbon atom constituting the adamantane skeleton when Ra is a hydrogen atom or a methyl group and Rb is a methyl group; and at least one substituent, in addition to the HO—C(Ra)(Rb)— group indicated in the formula (1), is bonded to the adamantane ring when one of Ra and Rb is a methyl group and the other is an ethyl group.
该发明的一种金刚烷甲醇衍生物由以下式(1)表示,其中Ra是氢原子或烃基;Rb是具有碳原子的烃基,该碳原子上至少有一个氢原子与相邻碳原子结合在一起;Rc、Rd和Re分别是氢原子、可能被保护基团保护的羟基或类似物;前提是当Ra是氢原子或甲基且Rb是甲基时,至少一个被保护基团保护的羟基与构成金刚烷骨架的至少一个碳原子结合在一起;当Ra和Rb中的一个是甲基而另一个是乙基时,除了式(1)中指示的HO—C(Ra)(Rb)—基团之外,至少有一个取代基与金刚烷环结合。
