摘要：

6-C-(3,3-Dimethyl-2-propen-1-yl) norwogonin was synthesized in 34% yield by direct C-prenylation of 5,7-dihydroxy-8-sulfooxy flavone using 4-bromo-2-methyl-2-buten in aqueous tetramethylammonium hydroxide. Among the minor products of the reaction, 6-C-(1,1-dimethyl-2-propen-1-yl) norwogonin, and traces of 7-O-(3-3-dimethyl-2-propen-1-yl) norwogonin were identified as well.
