An iridium-catalyzed annulation of chalcones with sulfonylazides via cascade C–H amidation and intramolecular aza-Michael addition was developed, affording a variety of 2-aryl-2,3-dihydro-4-quinolones in moderate to good yields. This reaction features easy operation, readily available starting materials, and the cascade formation of two C–N bonds in one pot.
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.
