Iridium-catalyzed arylative cyclization of alkynones by 1,4-iridium migration

, : Iridium-catalyzed arylative cyclization of alkynones by 1,4-iridium migration. Angewandte Chemie 53(25): 6523-6527

1,4-Metal migrations enable the remote functionalization of C-H bonds, and have been utilized in a wide variety of valuable synthetic methods. The vast majority of existing examples involve the 1,4-migration of palladium or rhodium. Herein, the stereoselective synthesis of complex polycycles by the iridium-catalyzed arylative cyclization of alkynones with arylboronic acids is described. To our knowledge, these reactions involve the first reported examples of 1,4-iridium migration.

We examined whether two purportedly face-specific effects, holistic processing and the left-side bias, can also be observed in expert-level processing of Chinese characters, which are logographic and share many properties with faces.
