Abstract

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.
