The 3-substituted 3-hydroxyindolin-2-ones with adjacent quaternarystereocenters were constructed in a single step via an efficient and stereoselective trapping of oxoniumylide with isatins. This reaction proceeds well in supercritical CO2 and is an example of the ability to use green approaches to efficiently construct polyfunctional molecules.
