One catalyst, three bonds: The title reaction between propiolic acids and unactivated olefins (see scheme; O red, Cl green) results in vicinal functionalization of the olefin, with the formation of new CC and CO bonds. Structurally complex 6,7,5‐tricyclic ring systems are formed in a single step by this cascade chloropalladation and formal [3+2] cycloaddition.
一个催化剂,三个键:丙酸与未活化的烯烃之间的标题反应(参见方案; O红,Cl绿)导致烯烃的邻位官能化,并形成新的CC和CO键。通过级联的氯钯和正式的[3 + 2]环加成反应,可在单个步骤中形成结构复杂的6,7,5-三环系统。
