Treatment of the title compound with various acidic and basic reagents brought about cleavage of the lactone ring to form unstable intermediates which recyclized in several manners. With strong acids the compound was transformed to γ-pyrones, with nucleophilic bases to resorcinols, and with non-nucleophilic bases to benzoylphloroglucinol. In the first two reactions the corresponding 3,5,7-triketo acid
用各种酸性和碱性试剂处理标题化合物导致内酯环裂解形成不稳定的中间体,该中间体以几种方式再循环。用强酸,该化合物被转化为γ-吡喃酮,亲核性碱被转化为间苯二酚,非亲核性碱转化为苯甲酰基间苯三酚。在前两个反应中,相应的3,5,7-三酮酸或酯是中间体。使用大量过量的螯合金属离子(Ca ++)导致可分离量的酯积累。提出了一种烯酮衍生物作为形成苯甲酰基间苯三酚的中间体。已经探索了标题吡喃酮的四种衍生物的反应。
