  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.

  The first facile one‐pot synthesis of sulfone‐containing oxindoles with easily accessible disulfides as the sulfonylating precursors is described. This reaction occurs smoothly under transition metal‐free conditions and shows excellent functional group tolerance, allowing the facile and efficient green synthesis of various sulfone‐containing oxindoles in aqueous solution.

  A highly efficient addition cyclization of Nmethyl-N-arylacrylamides with arylaldehydes or benzene-sulfonohydrazides was developed using a catalytic amount of the quaternary ammonium salt (TBAI) under metal-free conditions, leading to the carbonyl- and sulfone-containing oxindoles. Compared to previous Methods, which require excessive amounts of explosive organic peroxides and precious or toxic metal reagents, the present protocol, which gave access to 3,3-disubstituted oxindoles, is,a safe and green approach, resulting in the formation of various useful carbonyl- and sulfone-containing oxindoles in yields of 40-94%.
