摘要：

The interaction of gem-benzoylnitroethenes and gem-alkoxycarbonylnitroethenes with cyclic beta-diketones (dihydroresorcinol and dimedone) occurs as a one-pot process via sequential Ad(N) and S-N steps followed by denitration to give functionally substituted hexahydrobenzofurans. The intermediate products of the nucleophilic addition have been isolated in the reactions of gem-acetylnitroethenes with dihydroresorcinol. The structures of the synthesized compounds have been confirmed by IR, H-1, and C-13-{H-1} spectroscopy including the heteronuclear correlation experiments (H-1-C-13 HMQC and H-1-C-13 HMBC).
