mimics of natural compounds with strong antialgal activity, have been synthesized through cross-coupling by zerovalent Ni of 1-(2-iodo-5-methoxy)-phenylethanol or 2-iodo-5-methoxyacetophenone with iodoxylenes. The synthetic compounds had a hydroxyl or a methoxyl group at C-2 and two methyls in the C ring. Assays on the green alga Selenastrum capricornutum showed that all the compounds, except 2-methoxy-5
9,10-二氢菲和菲是具有强抗藻活性的天然化合物的模拟物,是通过零价Ni与1-(2-碘-5-甲氧基)-苯基乙醇或2-碘-5-甲氧基苯乙酮与零价镍交叉偶联而合成的碘代二甲苯。合成化合物在C-2处具有羟基或甲氧基,并且在C环中具有两个甲基。绿藻硒硒的测定表明,除2-甲氧基-5,7-二甲基菲外,所有化合物均对10(-4)M处的藻类生长产生强烈抑制作用。2-羟基-7,8-二甲基-9, 10-二氢菲和2-甲氧基-5,6-二甲基菲完全抑制了10(-5)M的生长。
