A novel, visible-light-induced 3-component synthesis of sulfonylated oxindoles from N-arylacrylamides, diaryliodonium salts and sulfur dioxide is described. The reaction provides simple access to a wide variety of 3-[(arylsulfonyl)methyl]indolin-2-ones in moderate to excellent yields under mild conditions at room temperature. The transformation proceeds in the absence of any external photosensitizer and enables an efficient, solely visible-light-driven fixation of sulfur dioxide.

A novel iron-catalyzed efficient approach to construct sulfone-containing oxindoles, which play important roles in the structural library design and drug discovery, has been developed. The use of readily available benzenesulfinic acids, an inexpensive iron salt as the catalyst, and air as the oxidant makes this sulfur incorporation protocol very efficient and practical.
