Synthesis of Euchrestaflavanone-A

The reaction of 2-methyl-but-3-en-2-ol with 5,7,4'-trihydroxy-3'-prenylflavanone (III) gives 5,7,4'-trihydroxy-3,6-diprenylflavanone (IV)(euchrestaflavanone-A), its monochroman (V) and a dichroman (VI).The flavanone III in turn has been prepared by the condensation of 6-hydroxy-2,4-dimethoxymethoxyacetophenone and 4-methoxymethoxy-3-prenylbanzaldehyde followed by cyclization and demethoxymethylation.
