N-acylazetidines are bench-stable, readily available amide acylating reagents, in which the reactivity is controlled by amide pyramidalization and strain of the four-membered ring. A general and highly chemoselective synthesis of ketones by the addition of organometallics to N-acylazetidines via stable tetrahedral intermediates offers wide substrate scope and exquisite selectivity for the ketone products.
