By sequential application of three palladium catalyzed reactions, namely, palladium catalyzed telomerization of butadiene with phenol, oxidation of terminal olefin of the telomer to methyl ketone, and palladium catalyzed elimination of phenol, an E and Z mixture of 5,7-octadien-2-one was prepared in a high yield. This compound was converted to an E and Z mixture of pyrethrolone. The Z form of pyrethrolone
通过依次应用三个钯催化的反应,即钯催化的丁二烯与苯酚的端粒化,端粒的末端烯烃氧化为甲基酮,以及钯催化的苯酚的消除,E和Z的5,7-辛二烯-2混合物-高产率地制备了一种。将该化合物转化为吡咯烷酮的E和Z混合物。通过与四氰基乙烯选择性加成形成E异构体,可将Z形式的吡咯烷酮与E异构体分离。
