An iron‐catalyzed electrophilicamination of sodium sulfinates with anthranils to generate N‐(2‐carbonylaryl) benzenesulfonamides with high atom efficiency under redox‐neutral conditions has been developed.
A new [3 + 4] cycloaddition of azaoxyallyl cations and anthranils has been achieved for rapid access to multisubstituted benzodiazepine derivatives. A variety of anthranils and α-halo hydroxamates were both effective substrates with simple operations under transition-metal-free conditions. The intriguing features of this method include its mild nature of the reaction conditions, high efficiency, broad

We report here a catalytic selective cage B4–H amination of o-carboranes employing an Ir(III) complex as a catalyst and anthranils as aminating agents, leading to a large class of B4-aminated o-carboranes with very high yields and a broad substrate scope under mild conditions without any oxidants. In these reactions, the carboxyl group serves as a traceless directing unit to determine the site selectivity

electrophilic anthranils was developed. This reaction proceeds in a highly regio- and chemoselective manner to afford γ, δ and ε-arylamines bearing a carbonyl or alcohol functionality with 100% atom efficiency. Preliminary mechanistic studies indicate that the chemoselectivity is controlled by the base and the alcohol product is derived from the base-catalyzed hydrosilylation of the CO bond.
