  Use of acyl substituents to favour 2,3-epoxidation of 5,7-dioxygenated flavones with dimethyldioxirane

  摘要：

  The reaction of 5,7-dimethoxyflavone with dimethyldioxirane (DMDO) gives the 2,3-epoxide rapidly at first. However, low levels of ring A hydroxylated by-products are also formed. With increasing proportions of DMDO, demethylation at C-5 becomes apparent and consumption of substrate is not matched by further significant build-up of the epoxide. Deactivation of ring A by the use of acyl groups removes this complication. 5,7-Diacylflavones give excellent yields of epoxides and monoacyl derivatives also react in good yield. Ionization potential mans derived from density functional theory calculations (B3LYP/6-31G*), provide good visual indicators of the relative reactivity of the key nucleophilic loci. The epoxides may be isolated as such, or transformed into flavonols by treatment with p-toluenesulfonic acid. (C) 2010 Elsevier Ltd. All rights reserved.

  The present invention relates to the use of a compound of general formula (1), useful for anti- ulcer activity. The compounds comprising substituted chrysin or substituted 7-hydroxy flavone analogs of the formula (1) wherein R' is selected from the group consisting of alkyl, alkenyl, alkoyl,benzoyl, hydrogen, carboxymethyl, acetamjde and R" is selected from the group consisting of H, OH, alkoxy, acetoxy and propenyl. More particularly, the present invention provides the use of analogs of 7-hydroxy flavone, to provide anti-ulcer against aspirin induced ulceration, pylorus ligation induced ulceration, ethanol induced ulceration and stress induced ulceration at a dose ranging between.1 -25mg/kg body weight.
