It is a convenient route towards o-(1-(1,3-diketone)) derivatives of benzoic acid, which are precursors of o-(heteroaryl)-benzoic acids. Further conversions with hydrazines and amidines lead to pyrazolo[ [5] , [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] ]isoindole and pyrimidine rings respectively. The structures of the obtained compounds were confirmed by X-ray structure determinations
摘要邻甲基羧基苯甲酰氯的邻苯二甲酸衍生物很容易酰化 N(1-环己烯基) 吗啉,并可能沿着经典路径酰化其他烯胺生成 1,3-二酮。这是获得邻-(1-(1,3-二酮))苯甲酸衍生物的便捷途径,它们是邻-(杂芳基)-苯甲酸的前体。与肼和脒的进一步转化导致吡唑并[ [5] , [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] ]异吲哚环和嘧啶环。所得化合物的结构通过X-射线结构测定证实。
