Synthesis of Desmodol, a Naturally Occurring Pyranoflavone

Desmodol (VI) isolated from the roots and stems of Desmodium caudatum DC has been synthesised. 3-Methylphloroacetophenone on veratroylation affords 2,4,6-triveratroyl-3-methylpholoroacetophenone (II) which is converted in two steps into flavones (III) and (IV).III on demethylation followed by treatment with 2-chloro-2-methyl-but-3-yne affords desmodol (VI), identical with the natural sample.
