The total synthesis of (±)-5,3'-dihydroxy-4'-methoxy-6",6"-dimethyl-chromeno-(7,8,2",3")-flavanone was first achieved through C-prenylation, cyclization, selective protection of phenolic hydroxyl group, aldol condensation, cyclization and deprotection starting from cheap isovanillin and 2,4,6-trihydroxyacetophenone, with total yield 6.7%. All structures of new compounds were confirmed by IR,1H NMR, MS and HRMS techniques.

Key words: 5,3'-dihydroxy-4'-methoxy-6",6"-dimethylchromeno-(7,8,2",3")-flavanone, total synthesis, pyranoflavanone
