A nonenzymatic kinetic resolution of sterically congested alcohols having a quaternary carbon atom in the β-position is reported. The catalyst system CuCl/NaOtBu/(R,R)-Ph-BPE together with a 3,5-xylyl-substituted tertiary hydrosilane enable enantioselective silylation of the hydroxy group. Several alcohols are obtained with good to excellent selectivity factors, and there are no other known straightforward methods to access these motifs.

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.

(A) A compound capable of forming a stable radical and selected from (A1) oxygen-atom-containing compounds each having a carbon-hydrogen bond at the adjacent position to an oxygen atom, (A2) carbonyl-group-containing compounds, and (A3) compounds each having a hydrocarbon group with a methine carbon atom is allowed to react with (B) a radical scavenging compound selected from, for example, (B1) unsaturated compounds, and (B2) compounds each having a hydrocarbon group with a methine carbon atom, in the presence of molecular oxygen by catalysis of, for example, an imide compound shown by the following formula (1): wherein each of R1 and R2 is a hydrogen atom or the like, where R1 and R2 may be combined to form a double bond, or an aromatic or non-aromatic ring; X is an oxygen atom or a hydroxyl group, to yield a product of an addition or substitution reaction of the compound (A) and the compound (B) or its oxidized product. The process can efficiently produce a variety of organic compounds by an addition or substitution reaction using molecular oxygen under mild conditions.
