摘要：

7,7"-Dimethoxy cupressuflavone, 7,7"-dimethoxy 5,5",4'',4''''''-tetraacetoxy cupressuflavone, cupressuflavone hexamethylether and 7,7",4'',4''''''-tetramethoxy cupressuflavone were synthesized by a new route via the corresponding bichalcones. It has the advantage over the synthesis via 8-iodo-apigenin trimethylether, that in the last step of demethylation of cupressuflavone hexamethylether, the possibility of Wessley-Moser rearrangement can be avoided.
