Sulfur Ylide Initiated [4 + 1]/[4 + 2] Annulation Reactions: A One-Pot Approach to Dibenzofuran Acrylate Derivatives
A one-pot approach has been developed for the synthesis of polysubstituted dibenzofuran acrylate derivatives from (E)-2-(2-nitrovinyl)phenols, sulfur ylides, and alkynes. This protocol was carried out under mild reaction condition without any precious catalysts in generally moderate to good yields....

Zusammenfassung: | A one-pot approach has been developed for the synthesis of polysubstituted dibenzofuran acrylate derivatives from (E)-2-(2-nitrovinyl)phenols, sulfur ylides, and alkynes. This protocol was carried out under mild reaction condition without any precious catalysts in generally moderate to good yields. Additionally, a plausible mechanism for the transformation was proposed. |
