实验步骤: Reflux 2-ethylcyclohexane-1,3-dione (30.6 g), pyridine (20 cc), benzene (372 cc) and a mixture of 1-diethylamino-6-m-methoxyphenylhexan-3-one and 6-m-methoxyphenylhex-1-en-3-one (40.3 g, produced by the distillation of the former substance) for 15 hours. Wash the cooled reaction mixture with water, 10% aqueous sulfuric acid, water, 10% aqueous sodium carbonate, water and brine, and filter. Evaporate the solvent to leave as residue 2-(6-m-methoxyphenyl-3-oxohexyl)-2-ethylcyclohexane-1,3-dione, 38.1 g, 56.2%. produced by the distillation of the former substance) for 15 hours Wash the cooled reaction mixture with water, 10% aqueous sulfuric acid, water, 10% aqueous sodium carbonate, water and brine filter Evaporate the solvent

实验步骤: Employing procedures similar to those described in Example 1, except that 2-ethylcyclohexane-1,3-dione is substituted for 2-methylcyclohexane-1,3-dione, 7-hydroxydec-1-en-3-one is produced.

实验步骤: 2-Ethyl-1,3-cyclohexanedione (15 g, 107 mmol), mesitylene (240 mL), and 5% Pd/C (7.8 g) were placed in a flask. The reaction mixture was stirred at 160° C. for two days. Filtration gave a crude product, which was purified by chromatography (EtOAc/Hexane) to give 2-ethyl-3-hydroxy phenol (2.2 g, 15%). Filtration gave a crude product, which was purified by chromatography (EtOAc/Hexane)

实验步骤: 1,3-Cyclohexanedione (10 g, 89.2 mmol), 40% aqueous CH3CHO (49.4 g, 445.9 mmol) were dissolved in methanol (40 mL) followed by addition of Hantzsch ester (22.7 g, 89.2 mmol) and pyridine (2.1 g, 18.74 mmol) under nitrogen. The resulting light yellow mixture was stirred at room temperature overnight, then concentrated to give crude product that was re-slurried in a mixture of CH2Cl2 (40 mL) and hexanes (60 mL) to furnish 2-ethyl-1,3-cyclohexanedione (8.6 g, 69%). concentrated to give crude product that
