Readily available C-acylated cycloalkanones undergo efficient Pd catalyzed ring closure/cross-coupling providing 7-substituted tetrahydroxanthones in a single operation. One of the synthesized derivatives (depicted) is shown to selectively kill pancreatic cancer (PANC-1) cells under conditions of nutrient deprivation indicating that the tetrahydroxanthone is responsible, in part, for the “antiausterity”
易于获得的C-酰化环烷酮经过有效的Pd催化的闭环/交叉偶联,可在一次操作中提供7个取代的四氢氧杂蒽。已显示一种合成的衍生物(已描述)在营养剥夺的条件下选择性杀死胰腺癌(PANC-1)细胞,这表明四氢黄酮在某种程度上负责天然存在的基加米星的“抗紧缩”作用。
