  A short and facile synthetic route to prenylated flavones. Cyclodehydrogenation of prenylated 2′-hydroxychalcones by a hypervalent iodine reagent

  摘要：

  The first synthesis of the prenylated flavones kanzonol-D (1), -E (3) and yinyanghuo-C (4) was accomplished by cyclodehydrogenation of the appropriately substituted 2'-hydroxychalcones 16, 14 and 11, respectively, in presence of phenyl-iodine(III) diacetate (PIDA) / potassium hydroxide in methanol. The synthesis of kanzonol-B (13) was also achieved from the 2'-hydroxychalcone 12. (C) 1998 Elsevier Science Ltd. All rights reserved.
