An acylating agent of the invention includes (A) a 1,2-dicarbonyl compound or its hydroxy reductant, (B) oxygen, and (C) at least one compound selected from (c1) a metallic compound and (C2) N-hydroxyphthalimide or another imide compound. As the 1,2-dicarbonyl compound or its hydroxy reductant (A), biacetyl, 2,3-butanediolor the like canbeused. As the metallic compound (c1), cobalt acetate, or another cobalt compound, for example, can be employed. By reacting an adamantane derivative or another compound having a methine carbon atom with the acylating agent, an acyl group can be introduced to the methine carbon atom with efficiency.
本发明的酰化剂包括(A)1,2-二羰基化合物或其羟基还原剂,(B)氧气,以及(C)至少选择自(c1)金属化合物和(C2)N-羟基邻苯二甲酰亚胺或另一种亚胺化合物的化合物。作为1,2-二羰基化合物或其羟基还原剂(A),可以使用双醋酸、2,3-丁二醇等。作为金属化合物(c1),可以采用乙酸钴或另一种钴化合物。通过将金刚烷衍生物或另一种具有亚甲基碳原子的化合物与酰化剂反应,可以高效地在亚甲基碳原子上引入酰基。
