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-butanediol or the like can be used. 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)氧和(C)至少一种选自(c1)金属化合物和(C2)N-羟基邻苯二甲酰亚胺或另一种酰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),可以使用生物乙酰基、2,3-丁二醇或类似物。作为金属化合物(c1),可以使用醋酸钴或其他钴化合物等。将金刚烷衍生物或其他具有甲烷碳原子的化合物与酰化剂反应,可以有效地将酰基引入甲烷碳原子。
