Yield:-
Reaction Conditions:
Stage #1:maleic anhydride with (S)-BINOL-Silica Hybrid (BSH) in dichloromethane at 20; for 0.166667 h;Diels-Alder Cycloaddition;
Stage #2:cyclopenta-1,3-diene in dichloromethane at 20; for 2 h;Overall yield = 85 %; Optical yield = 84 %de;Diels-Alder Cycloaddition;
Steps:
2.3 General Procedure for the AsymmetricDiels-Alder Cycloaddition in the Presenceof the Catalyst (BSH)
General procedure: Dienophile (1 mmol) and 0.15 g of the catalyst (BSH) were added to CH2Cl2 (5 mL) and the mixture was stirred at room temperature. After 10 min, 6 mmol cyclopentadien (Cp) was added to the mixture. 2 h later, the reaction mixture was filtered and the solid was washed with CH2Cl2. The organic phase was evaporated in vacuo and purified by column chromatographyto afford the pure cycloadduct 3, 5 and 7.
