Some Reactions of β-Aroylacrylic Acid Epoxides
Elkasaby, M. A.,Noureldin, N. A.
, p. 366 - 368 (2007/10/02)
β-Aroylacrylic acids (I) on reaction with hydrogen peroxide give α,β-epoxy-β-aroylacrylic acids (II) which on treatment with sodium hydroxide afford a mixture of arylmethyl 1,2-diketone (III) and arylmethyl glycollic acid (IV).The mixture is separated bei
