afforded benzyl 7-(3,5-dimethoxyphenylacetoxy)octanoate (6) in 70% yield, which is the precursor of Curvularin (4). The ester (12) was easily prepared from the butadiene telomer obtained by the palladium-catalyzed reaction of butadiene with acetic acid.
用7-羟基辛酸苄酯(12)进行钯催化的3,5-二甲氧基苄基氯(13)的羰基化反应,制得7-(3,5-二甲氧基苯基乙酰氧基)辛酸苄酯(6),产率为70%,是Curvularin(4)的前体。 )。酯(12)易于由通过丁二烯与乙酸的钯催化反应获得的丁二烯调聚物制备。
