Reaction Steps

1-Trimethylsilyloxy-1-(thiophen-3-yl)ethylene (7.0 mmol; prepared according to J. Chem. Soc., Perkin Trans. I 1989, 1585) and CsF (0.27 g, 1.76 mmol) were added to a suspension 1-(2-hydroxyphenyl)-3-(3,4-methylenedioxyphenyl)-2-propen-1-one on Wang resin (2.0 g, 1.76 mmol) in dimethyl sulfoxide (30 mL). The reaction mixture was heated to 70° C. for 3 h and the reaction was quenched with 10% AcOH/CH2Cl2. The resin was filtered, washed with DMF (×2) and alternating MeOH and CH2Cl2(×5), and dried under high vacuum overnight to give 1-(2-hydroxyphenyl)-3-(3,4-methylenedioxyphenyl)-5-(thiophen-3-yl)-1,5-pentanedione on Wang resin.
