of 1,7‐octadiene as an in situ source of ethylene led us to develop a novel multicomponent tandem cross‐enyne metathesis (CEYM)‐Diels–Alder reaction. The process can be considered a relay metathesis, in which the ethylene liberated in the ring‐closing metathesis (RCM) of 1,7‐octadiene initiates the tandem sequence. Aliphatic, aromatic, and fluorinated alkynes and several dienophiles are compatible with
使用1,7-辛二烯作为乙烯的原位源,使我们开发了一种新颖的多组分串联跨烯炔复分解(CEYM)-Diels-Alder反应。该过程可以被认为是一种中继复分解,其中在1,7-辛二烯的开环复分解(RCM)中释放的乙烯启动了串联序列。脂族,芳族和氟化炔烃和几种亲二烯体与该方法相容,这对于芳族炔烃特别有效。该方法构成了CEYM相关反应中Mori条件的一种有用变体。
