Claims (14)

다음 구조식(Ⅲ)으로 대표되는 화합물의 4'위치의 하이드록실기 또는 1 및 4'위치의 하이드록실기를 저급 알카노산, 지방족아미노산, 하이드록시 치환된 디카복실산 또는 니코틴산의 반응성을 유도체로 처리하여 아실화하거나 구조식(Ⅲ)의 4'위치중 하이드록실기를 단당류의 반응성 유도체로 처리하여 글리코실화 하거나 2', 4', 6'-트리하이드록시-2-알콕시아세토페논을 비스-(4-아세트아미도벤조산)무수화물 및 4-아세트 아미도벤조산의 알카리 금속염과 반응시키고 결과의 화합물을 알카리 금속 하이드록사이드로 처리하여 4'-아미노-5, 7-디하이드록시-3-알콕시플라본을 얻으며 필요하면 상기 화합물을 디아조알칸으로 처리하여 그의 7-알콕시화합물을 얻음을 특징으로 하여 다음 구조식(Ⅱ)의 3-알콕시플라본 유도체를 제조하는 방법.By reacting the hydroxyl group at the 4'position or the hydroxyl group at the 1'and 4'position of the compound represented by the following structural formula (III) as a derivative of lower alkanoic acid, aliphatic amino acid, hydroxy substituted dicarboxylic acid or nicotinic acid Acylated or treated with a hydroxyl group in the 4'position of structural formula (III) as a reactive derivative of a monosaccharide, or glycosylated or 2', 4', 6'-trihydroxy-2-alkoxyacetophenone bis-(4- Acetamidobenzoic acid) reacted with an alkali metal salt of anhydride and 4-acetamidobenzoic acid, and the resulting compound was treated with an alkali metal hydroxide to give 4'-amino-5, 7-dihydroxy-3-alkoxyflavone. Obtaining and, if necessary, treating the compound with diazoalkane to obtain its 7-alkoxy compound, thereby producing a 3-alkoxyflavone derivative of the following structural formula (II). 상기 구조식에서In the above structural formula R10은 하이드록시, 저급알카노일옥시, 저급알콕시 카보닐옥시 또는 니코티노일옥시이고R 10 is hydroxy, lower alkanoyloxy, lower alkoxy carbonyloxy or nicotinoyloxy R20은 하이드록시 또는 저급알콕시이며R 20 is hydroxy or lower alkoxy R40은 수소 또는 저급알콕시,R 40 is hydrogen or lower alkoxy, R50은 하이드록시, 저급알카노일옥시, 아미노아실옥시, 글리코실옥시, 하이드록시-치환된 디카복실산 잔기, 아미노, 니코티노일옥시 또는 저급알콕시 카보닐옥시이며R 50 is hydroxy, lower alkanoyloxy, aminoacyloxy, glycosyloxy, hydroxy-substituted dicarboxylic acid residue, amino, nicotinoyloxy or loweralkoxy carbonyloxy R60은 저급알콕시이다.R 60 is lower alkoxy. (단 R10이 아세톡시일때 R50은 아세톡시가 아니며 R50이 하이드록시일때 R60은 메톡시가 아니다)(Where R 10 is acetoxy when R 50 is not an acetoxy R 50 is hydroxy when R 60 is not a methoxymethyl) R21은 저급알콕시이고R 21 is lower alkoxy R41는 수소 또는 저급알콕시이며R 41 is hydrogen or lower alkoxy R61은 저급알콕시이다.R 61 is lower alkoxy. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: Disclosure is based on the original application.
