Reaction Steps
3-Phenylmethylene-5-butyldihydro-2(3H)-furanone was prepared by reacting 3-acetyl-5-butyldihydro-2(3H)-furanone with sodium hydroxide and benzaldehyde in accordance with the procedure described in Example I. The crude product (64.5% yield) was recovered by distillation of the reaction mixture at 25°-147° C. (0.04 mm/Hg) to remove light ends. The structure was confirmed by proton nuclear magnetic resonance spectroscopy.
