The yellowish aphid pigment furanaphin, isolated from Aphis spiraecola and possessing cytotoxicity against HL-60 (human promyelocytic leukemia-60) cells, was synthesized by utilizing the Fries rearrangement assisted with a BF3·2AcOH complex as a key step. It was confirmed that the complex effectively mediated the reaction even though the compounds had an electron-withdrawing substituent.
以BF3·2AcOH复合物辅助的Fries重排为关键步骤,从Aphis spiraecola中分离出对HL-60(human promyelocyticemia-60)细胞具有细胞毒性的黄色蚜虫色素呋喃酚。证实即使化合物具有吸电子取代基,该配合物也有效地介导了反应。
