Abstract
NEW MATERIAL:An epoxide derivative of formula I (X is H, halogen, lower alkyl, lower alkyloxy, or hydroxy).
EXAMPLE: 1,2-Diphenyl-3,5-dioxo-4-(2',3'-dioxo-3'-methyl)-butyl-pyrazolidine.
USE: An intermediate of a novel antiphlogistic agent. The compound also has antiphlogistic activities.
PROCESS: The objective compound I can be prepared by reacting 1 equivalent of a 1,2-diphenyl-3,5-dioxo-4-prenyl-pyrazolidine II with 0.8W2.0, pref. 1.0W1.5 equivalent of a peroxide, pref. selected from peracids, alkylhydroperoxides, and hydrogen peroxide.
