Özet

In this work we used an efcient and simple synthesis for the preparation of new indolhydroxy derivatives that has been performed by the reduction reaction of 2-nitrocinnamic acid or 2-nitrophenyl pyruvic acid with anhydrous stannous chloride (SnCl2) as a metal catalyst in diferent alcoholic solvents. During this transformation there was the involvement of intramolecular elimination cyclization. In the case of the reduction of 2-nitrocinnamic acid we obtained hydroxyindole plus hydroxyquinoline, on the other hand, the reduction of 2-nitrophenyl pyruvic acid gives hydroxyindole only, the products were obtained in suitable yields. The structures of all the synthesized compounds were fully characterized by diferent spectroscopic techniques such as 1 H NMR, 13C NMR. In addition, the obtained products have been tested in silico against anti-human immunodefciency virus type 1 (HIV-1) and SARS-CoV-2 virus. The outcomes of this work are very promising to develop more efcient antiviral compounds, indicating that these products may be a probable drugs for the SARS-CoV-2.
