反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a 100 mL of two neck RB flask was charged ethyl 3-(4-hydroxyphenyl)-3-phenylpropanoate (0.6 g, 2.2 mmol) and (4-{[(2Z)-2-(methoxyimino)-2-phenylethyl]oxy}phenyl)methanol (0.6 g, 2.2 mmol) in 20 mL of THF. To this added triphenyl phosphine (0.755 g, 2.88 mmol) at 0° C. and added DIAD (0.59 g, 2.88 mmol) portion wise over a period of 15 min at 0° C. After 12 h of stirring at RT, the mixture was diluted with Ethyl acetate, washed with water and brine solution successively. Organic phase was dried over anhydrous Na2SO4 and concentrated to afford yellow oil as product (0.6 g, yield: 52.17%); 1H NMR (300 MHz, DMSO-d6): δ 7.57-7.60 (m, 2H), 7.06-7.31 (m, 12H), 6.84-6.86 (m, 4H), 5.12 (s, 2H), 4.84 (s, 2H), 4.39-4.45 (t, 1H), 3.86-4.01 (m, 5H), 2.92-2.95 (d, 2H), 1.00-1.05 (t, 3H). washed with water and brine solution successively Organic phase was dried over anhydrous Na2SO4 concentrated to afford yellow oil as product (0.6 g, yield: 52.17%)

实验步骤: A 500 mL par shaker charged with ethyl (2Z)-3-(4-hydroxyphenyl)-3-phenylprop-2-enoate (1 g, 3.7 mmol) in Ethanol/Ethyl acetate was degasified with nitrogen for 2 min. Added 10% of Pd/C (0.4 g, 10%) and applied 50 psi of H2 pressure for 3 h. Reaction mixture was filtered through celite pad and washed the pad with excess Ethanol. Organic phase was dried over anhydrous Na2SO4 and concentrated to afford oil as product. (0.6 g, Yield: 60.1%); 1H NMR (300 MHz, DMSO-d6): δ 9.21 (s, 1H), 7.07-7.29 (m, 7H), 6.63-6.66 (d, 2H), 4.29-4.34 (t, 1H), 3.89-3.96 (q, 2H), 3.02-3.03 (d, 2H), 0.99-1.04 (t, 3H) for 3 h Reaction mixture was filtered through celite pad washed the pad with excess Ethanol Organic phase was dried over anhydrous Na2SO4 concentrated to afford oil as product
