Chiral dicationic palladium complex-catalyzed vinylation and dienylation of glyoxylate with vinylsilanes and dienylsilanes to produce highly optical active allylic alcohols has been achieved. The advantages of this reaction are that the chiral palladium catalyst is readily employed and that vinylsilanes as nucleophiles are easily synthesized, storable, and air- and moisture-stable.
已经实现了手性双阳离子钯配合物催化乙醛酸与乙烯基硅烷和二烯基硅烷的乙烯基化和二烯化,以生产高光学活性的烯丙醇。该反应的优点是手性钯催化剂易于使用,并且乙烯基硅烷作为亲核试剂易于合成、储存、空气和湿气稳定。
