Abstract

Abstract: Iodine(III) reagents are used in catalytic one‐pot reactions, first as both oxidants and substrates, then as cross‐coupling partners, to afford chiral polyfunctionalized amines. The strategy relies on an initial catalytic auto C(sp 3 )−H amination of the iodine(III) oxidant, which delivers an amine‐derived iodine(I) product that is subsequently used in palladium‐catalyzed cross‐couplings to afford a variety of useful building blocks with high yields and excellent stereoselectivities. This study demonstrates the concept of self‐amination of the hypervalent iodine reagents, which increases the value of the aryl moiety.
