This paper describes a new synthetic approach for biologically interesting geranylated acetophenones. The first total syntheses of 1-(5-geranyloxy-7-hydroxy-2,2-dimethyl-2H-chromen-8-yl)ethanone and 1-[5-geranyloxy-7-hydroxy-2-methyl-2-(4-methylpent-3-enyl)-2H-chromen-8-yl]ethanone, isolated from Melicope semecarpifolia, were carried out starting from commercially available 2,4,6-trihydroxyacetophenone.
本文描述了一种合成具有生物学意义的香叶基化苯乙酮的新方法。首次完成了从商品化的2,4,6-三羟基苯乙酮出发,合成了从**山胡椒叶**中分离得到的1-(5-香叶氧基-7-羟基-2,2-二甲基-2H-色烯-8-基)乙酮和1-[5-香叶氧基-7-羟基-2-甲基-2-(4-甲基戊-3-烯基)-2H-色烯-8-基]乙酮的全合成。
