Indole derivativesR 0140 Efficient Reductive Acylation of 3-Nitroindoles. — The reduction of substrates (I)
by hydrogen in the presence of carboxylic acid anhydrides provides good to excellent yields of 3-carboxamidoindoles (III), whereas 2-nitroindoles give lower yields of the corresponding products (VII). The method is further applied to the synthesis of pyrro-lylindole (V). — (ROY, S.; ROY, S.; GRIBBLE*, G. W.; Tetrahedron Lett. 49 (2008) 9, 1531-1533; Dep.
