反応手順

The reaction was repeated using 3-acetyl-dihydro-2(3H)-furanone, sodium hydroxide and benzaldehyde to produce 3-phenyl methylene-dihydro-2(3H)-furanone. The crude yellow solid obtained from the reaction was recrystallized from chloroform to recover 3-phenylmethylene-dihydro-2(3H)-furanone, a yellow crystalline solid melting at 116° C. Proton and carbon nuclear magnetic resonance spectra for the product were as follows:
