An approach to construct the oxo‐dehydrorotenoids via direct lactonization of isoflavone‐2‐carboxylic acids is reported. The application of this method for the first total syntheses of the natural products, stemonone, 6‐oxo‐dehydroelliptone, rotenonone, and 6‐oxo‐6a,12a‐dehydrodeguelin, are demonstrated. The series of oxo‐dehydrorotenoids was also evaluated for their biological activities.
据报道,有一种通过异黄酮2-羧酸直接内酯化来构建羰基-脱氢类胡萝卜素的方法。演示了该方法在天然产物首次合成中的应用,该合成物为马酮酮,6-氧代-脱氢Elliptone,鱼藤酮和6-氧代-6a,12a-脱氢deguelin。还评估了一系列氧-脱氢类胡萝卜素的生物活性。
