Regiochemistry of Deoxygenation of Nitro-Containing Isatins with Tris(diethylamino)phosphine

摘要

Isatin derivatives containing a 4-nitrophenyl group in the side chain or a nitro group in the aromatic fragment reacted with tris(diethylamino)phosphine to give the corresponding isoindigo derivatives with high yields and chemoselectivity.
