Two novel acetophenones, 4-(1′-geranyloxy)-2,6-dihydroxyacetophenone 1 and 4-(1′-farnesyloxy)-2,6-dihydroxyacetophenone 2 isolated from the fruit of Evodia merrillii and from the aerial parts of Borronia ramosa respectively, have been synthesized starting from 2,4,6-trihydroxyacetophenone 3; the key step in their total synthesis is the regioselective alkenylation onto the intermediate 6 with alkenyl
从 Evodia merrillii 果实和 Borronia ramosa 地上部分分离的两种新型苯乙酮,4-(1'-geranyloxy)-2,6-dihydroxyacetophenone 1 和 4-(1'-farnesyloxy)-2,6-dihydroxyacetophenone 2分别以2,4,6-三羟基苯乙酮3为原料合成;它们全合成的关键步骤是用烯基溴对中间体 6 进行区域选择性烯基化。
