Pyridine N-oxide derivatives represent a new class of anti-HIV compounds, for which some members exclusively act through inhibition of HIV-1 reverse transcriptase and thus characteristically behave as non-nucleoside reverse transcriptase inhibitors. Other members act, additionally or alternatively, at a post-integrational

Enantioselective nitrone cycloadditions with 2-alkenoyl pyridine N-oxides as dipolarophiles have been reported. The reaction is catalyzed by Cu(II)-BOX complexes to give the expected isoxazolidine products with high diastereo- and enantioselectivity.
