Three-Component Reactions of Polynitromethanes with Alkynes. The First
of gem-Dinitroaziridines. — The reaction between tetranitromethane or
20- 097 Synthesis
bromotrinitromethane with bicyclobutylidene generates a dinitroate intermediate. The
latter undergoes 1,3-dipolar cycloaddition to the alkynes (III) followed by rearrangement of the resulting 2,3-dihydroisoxazoles to yield highly functionalized aziridines
(IV). A second alternative to generate a dinitroate is achieved from trinitromethane (V)
and diazomethane. — (BUDYNINA, E. M.; AVERINA, E. B.; IVANOVA, O. A.;
