Synthesis and biological activity of potential antiviral compounds through 1,3-dipolar cycloadditions. Part 2: nitrones, nitrile oxides and imines, and other 1,3-dipoles

Prominent in the current stage of drug development, antiviral compounds can be efficiently prepared through cycloaddition reactions. This review reports the use of 1,3-dipolar cycloadditions of nitrones, nitrile oxides and imines and other 1,3-dipoles in the light of their application for the preparation of synthons in the design and synthesis of compounds that were tested for their antiviral activities against a variety of viruses. Since nitrile oxides represent valuable precursors of nitrosocarbonyl intermediates, their use in the synthesis of antiviral compounds is reported. The products obtained from these pericyclic reaction approaches were tested for their activities in terms of blocking the virus replication and the relevant biological data are highlighted.
