antiarthritis activity. Further biological studies have been limited because of the limited availability of 1 from natural sources. Herein the first total synthesis of 1 in an overall yield of 8.3% is described. The synthesis involved the regio- and stereoselective glycosylation–Fries-type O-to-C rearrangement to construct the C-aryl glycosidic linkage, followed by a Baker–Venkataraman rearrangement and cyclodehydration
来自Acryculon aciculatus的新的黄酮-糖苷aciculatin(1)已被证明具有细胞毒,抗炎和抗关节炎活性。由于天然来源1的可用性有限,因此进一步的生物学研究受到了限制。在此描述了1的第一次总合成,总产率为8.3%。合成所涉及的区域选择性和立体选择性糖基化薯条型ø -到- Ç重排构造Ç -芳基糖苷键,接着是贝克-卡塔拉曼重排和环化脱水以形成黄酮支架。
