A novel tandem Blaise/Pinner-type reaction for the one-pot synthesis of pyrimidin-4-ones is described. The Blaise reaction intermediate, formed by addition of a Reformatsky reagent to a nitrile, reacted with a second nitrile chemoselectively in the presence of a catalytic amount of Cu(OAc)2 to afford pyrimidin-4-ones.
描述了一种用于嘧啶-4-酮一锅合成的新型串联Blaise / Pinner型反应。在催化量的Cu(OAc)2存在下,通过向腈中加入Reformatsky试剂而形成的Blaise反应中间体与第二个腈发生化学选择性反应,得到嘧啶-4-酮。
