Cobalt‐Catalyzed Temperature‐Dependent Annulation of 3‐Aryl‐1,2,4‐oxadiazolones with 1,3‐Diynes: An Approach to π‐Conjugated Molecules

A Cobalt‐catalyzed annulation of 3‐aryl‐1,2,4‐oxadiazolones with 1,3‐diynes has been developed, in which reaction temperature variation considerably affects the cyclization orientation and afforded structurely distinctive products in good yields and high regioselectivity. Additionally, the late‐stag...
