Nucleophilic addition of nitroethylene with various carbanions followed by treatment with chlorotrimethylsilane gave the corresponding silyl nitronate as a 1,3-dipole, which reacted with a monosubstituted alkene (3-buten-2-one or methyl 2-propenoate) to give functionalized 4,5-dihydroisoxazole derivatives in a one-pot procedure.
