View Patent ↗To provide an alcohol compound containing fewer impurities at a high yield by conducting the following steps: a hydroboration process in which a reaction mixture is obtained by reacting in a solvent a compound represented by formula (C) and a boron agent selected from a group of diborane and borane complexes; and an oxidation process in which the pH of the reaction mixture is set at 0.5 to 4, which is conducted after treating the reaction mixture with hydrogen peroxide. In the formula, A 1 to A 6 are each independently a hydrogen atom, methyl group or ethyl group, and X is an oxygen atom, sulfur atom, methylene group or ethylene group.
1. A method for producing an alcohol compound represented by formula (D), the method comprising:
a hydroboration process comprising reacting in a solvent a compound represented by formula (C) and a boron agent that is a borane dimethylsulfide complex or a borane-1,2-dimethoxyethane complex, to obtain a reaction mixture; and
an oxidation process comprising treating the reaction mixture with hydrogen peroxide, and then adjusting a pH of the reaction mixture to be within a range of 0.5 to 4:
wherein:
A 1 to A 6 are each independently a hydrogen atom, methyl group or ethyl group; and
X is an oxygen atom, sulfur atom, methylene group or ethylene group.
2. The method of claim 1 , wherein the boron agent is a borane dimethylsulfide complex.
3. The method of claim 1 , further comprising isolating the alcohol compound represented by formula (D) by recrystallizing the reaction mixture by adjusting the pH of the reaction mixture to be 5 to 9 after the oxidation process.
4. The method of claim 1 , further comprising forming the compound represented by the formula (C) by reducing a compound represented by formula (4) with sodium borohydride,
wherein an amount of sodium borohydride is set at a mole ratio of 0.7 to 0.95 relative to the compound represented by formula (4):
wherein R 11 to R 16 are each independently a hydrogen atom, methyl group or ethyl group; and X is an oxygen atom, sulfur atom, methylene group or ethylene group.
5. A method for producing a (meth)acrylate ester, the method comprising:
producing an alcohol compound represented by formula (D) from a compound represented by formula (C) by the method according to claim 1 ; and
performing an esterification reaction of the compound represented by formula (D) to obtain a (meth)acrylate ester represented by formula (A):
wherein in all of formulae (A), (C), and (D) R 1 is a hydrogen atom or a methyl group, A 1 to A 6 are each independently a hydrogen atom, methyl group or ethyl group, and X is an oxygen atom, sulfur atom, methylene group or ethylene group.
6. The method of claim 5 , further comprising, prior to said producing an alcohol compound represented by formula (D), forming the compound represented by the formula (C) by reducing a compound represented by formula (4) with sodium borohydride,
wherein an amount of sodium borohydride is set at a mole ratio of 0.7 to 0.95 relative to the compound represented by formula (4):
wherein R 11 to R 16 are each independently a hydrogen atom, methyl group or ethyl group; and X is an oxygen atom, sulfur atom, methylene group or ethylene group.
7. The method of claim 1 , wherein the boron agent is a borane-1,2-dimethoxyethane complex.
8. The method of claim 1 , wherein X is an oxygen atom.
9. The method of claim 1 , wherein X is a sulfur atom.
10. The method of claim 1 , wherein X is a methylene group.
11. The method of claim 1 , wherein X is an ethylene group.
