An Efficient and Mild Synthesis of Tetrahydro-4H-indol-4-one Derivatives via a Domino Reaction in Water
摘要:
An efficient domino approach for the synthesis of tetrahydro-4H-indol-4-one derivatives has been established. The use of catalytic amount of l-proline in water at 60 degrees C makes it quite simple, more convenient, and environmentally benign.

tetrahydro-1H-indol-4(5H)-one using heterogeneous Brønsted base silica sodium carbonate (SSC) as a catalystundersolvent-freeconditions. In comparison to the conventional methods, this efficient green protocol provides remarkable advantages such as good to excellent yields, shorter reaction time, low cost, and easy workup procedure and bypasses the use of hazardous transition-metal catalysts and organic solvents
