General Experimental Procedure To a stirred solution of aldehyde 1 (1.2 mmol, catalyst 11 (0.20 mmol, p-fluorophenol (0.20 mmol, and SiO2 (100 mg) in CH2Cl2 (10 ml) was added α,β-unsaturated trifluoromethyl ketones (1.0 mmol) at r.t. and the reaction mixture was stirred for the time as specified in Table 2 (monitored by TLC, The resulted mixture was directly purified by column chromatography on silica gel to give product 3. Jones reagent was added to the solution of 3 (0.8 mmol) in acetone (15 mL) at r.t. until the salmon pink of the solution did not disappear in one minute. The mixture was stirred at r.t. for 2 h and then quenched by MeOH (1 mL) and H2O (2 ml, The resulted mixture was extracted with Et2O (3 x 10 ml) and dried over Na2SO4. After removal of the solvent, the crude product of 7 was obtained and used in the next step directly without
