Promoting Reductive Tandem Reactions of Nitrostyrenes with Mo(CO)6 and a Palladium Catalyst To Produce 3H-Indoles
摘要:
The combination of Mo(CO)(6) and 10 Mol % of palladium acetate catalyzes the transformation of 2-nitroarenes to 3H-indoles through a tandem cyclization-[1,2] shift reaction of in situ generated nitrosoarenes. Mo(CO)(6) appears to have dual roles in this transformation generate generate CO and promote C-N bond formation to increase the yield of the N-heterocycle product.

installation of the methylamino group to (hetero)aromatic boronic acids and esters. This method also provides for a unified synthetic approach to isotopically-labeled N-methylanilines from various stable isotopologues of nitromethane (i.e. CD3NO2, CH315NO2 and 13CH3NO2), revealing this easy-to-handle compound as an versatileprecursor for the direct installation of the methylamino group.
