The synthesis of flavanone A 8, a constituent of the leaves and bark of Milletia ovalifolia is described. β-Resacetophenone 1 on treatment with methoxymethyl chloride afford 2,4-dimethoxymethoxyacetophenone 2 which on nuclear prenylation yield 2,4-dimethoxymethoxy-3,5-di-C-prenylacetophenone 5. Alkaline condensation of 5 with benzaldehyde give 2',4'-dimethoxymethoxy- 3',5'-di-C-prenylchalcone 6. 2',4'-Dihydroxy-3',5'-di-C-prenylchalcone 7 obtained by the demethoxymethylation of 6, on treatment with NaOAc/EtOH furnish 7-hydroxy-6,8-di-C- prenylflavanone (8, flavanone A).
