An efficient oxidative cross-coupling reaction between 1,3-diarylpropenes and indoles in the presence of palladium chloride was achieved with 2,3-dichloro-5,6-dicyanoquinone (DDQ) as oxidant. The reaction afforded 1,3-diphenylallylindoles in moderate to high yields under mild conditions, thus providing a novel methodology to synthesize the respective products.
以2,3-二氯-5,6-二氰基醌(DDQ)为氧化剂,在氯化钯存在下,实现了1,3-二芳基丙烯和吲哚之间的有效氧化交叉偶联反应。该反应在温和条件下以中等至高收率提供了1,3-二苯基烯丙二烯,因此提供了合成相应产物的新颖方法。
