Allyl aryl ethers and allyl phenol derivatives were prepared starting from commercial or synthetized phenols. Either Williamson reaction or Et2AlCl catalyzed Claisen rearrangement was performed to obtain the polyoxygenated molecules. The pivotal allyl phenols were then modified by methylation, iodocyclization or electrophilic aromatic iodination to afford the polyoxygenated derivatives in good to excellent
从商业或合成的苯酚开始制备烯丙基芳基醚和烯丙基苯酚衍生物。进行威廉姆森反应或Et 2 AlCl催化的克莱森重排以获得多加氧分子。然后通过甲基化,碘环化或亲电子碘化碘化对枢轴烯丙基苯酚进行改性,从而以良好或优异的收率得到多氧化衍生物。此外,还研究了它们对革兰氏阳性和革兰氏阴性细菌的抗菌性能。
