Carbenoid-based N-H insertions have undergone significant development with respect to C-N bond formation in recent years. However, the existing methods suffer from unstable starting materials, expensive metal catalysts and organic solvents. Herein, insertion of sulfoxonium ylides into arylamines under metal-free conditions has been developed. The method employs water as solvent at mild temperature and is amenable to the late-stage modification of structurally complex bioactive compounds.

Aryl- and aliphatic-substituted 3-hydroxyprolines and various other amino esters are conveniently prepared by [RuCI2(p-cymene)] 2-catalyzed one-pot intramolecular and intermolecular carbenoid N-H insertion reactions, respectively, and the prolines are formed with high diastereoselectivities. The catalytic reactions are tolerant toward air/moisture, and the product yields are insensitive to the organic solvents used.
