Abstract
A convenient, one-pot synthesis of 2,3-diarylindoles 4 is described via a b is-Suzuki palladium-catalyzed cross coupling of 2,3-dihalo-1-(phenylsulfony l)indoles 1 with arylboronic acids 2, followed by cleavage of the N-protect ing group to give 4. The anti-inflammatory drug indoxole (4c) is prepared i n high yield. (C) 2000 Elsevier Science Ltd. All rights reserved.
