—— | 1'H,3H-[2,3'-biindol]-3-one | 69247-70-7 | C16H10N2O | 246.268 |
A simple, convenient, and efficient synthesis of 2-(1H-indol-3-yl)-2,3′-biindolin-3-one derivatives has been developed by the oxidative trimeric reaction of indoles using the TEMPO/CuCl2 catalyst system under ambient air. This methodology provides an alternative approach for the direct generation of all-carbon quaternary centers at the C-2 position of indoles.
