Abstract

1,1-Diaryl-ethylene oxides(Ia-c) react with ethyl cyanoacetate or malononitrile and ethyl aceto- acetate in the presence of sodium ethoxide to give y, r-diary1-4-cyano(Ila-c and,Vr-diaryl-a-aceto(IIIa-c)-Y -butyrolactones, respectively. Alkaline hydrolysis of II afforded the corresponding -carboxy-butyrolac- tones (IVa-c). Decarboxylation of IV yielded, r,' - diaryl-Y-butyrolactones(Va-c). Also, (Ia-c) react with sodioacetylacetone to give 3-acetyl-5,5-diaryl- 5-hydroxy-2-pentanones (Via-c). The structure elucidation of the products is based on chemical transformations, spectral and chemical data.
