Graphical Abstract

In an impressive show of independence, iodonium ylides underwent direct cyclization with unmodified tertiary aryl amines (see scheme). The transformation, which was developed on the basis of the exceptional finding that iodonium ylides could cleave the C(sp3)−H bonds of tertiary aryl amines, proceeded in the absence of a transition-metal catalyst and without the use of an additional initiator/oxidant.

Abstract

Described herein is a direct cyclization of simple tertiary aryl amines with iodonium ylides leading to a broad range of N-heterocycles. Completely different from the known reactivity of iodonium ylides, the finding reported herein is that an iodonium ylide is capable of cleaving a C(sp3)−H bond and accepting two hydrogen atoms of a tertiary aryl amine, thus inducing a novel cyclization process. This transformation can proceed without the assistance of a transition-metal catalyst and eliminates the need for the premodification of the amine or the use of an additional initiator/oxidant.
