  Direct Oxidative Coupling of Enamides and 1,3-Dicarbonyl Compounds: A Facile and Versatile Approach to Dihydrofurans, Furans, Pyrroles, and Dicarbonyl Enamides

  摘要：

  An efficient manganese(III)-mediated oxidative coupling reaction between a-aryl enamides and 1,3-dicarbonyl compounds has been developed. A series of dihydrofurans and dicarbonyl enamides were synthesized in moderate to good yields. Moreover, these dihydrofurans could be readily transformed into the corresponding furans and pyrroles via the Paal-Knorr reaction.

  method for the synthesis of tri-substituted furans has been developed based on Cu(I)-catalyzed reaction of terminal alkynes with β-keto α-diazoesters. This method for the synthesis of 2,3,5-trisubstituted furans is operationally simple and applicable to wide substrate scope. Moreover, this synthesis employs cheap Cu(MeCN)4PF6 as the catalyst and no additional ligand is needed. Similar reaction has also been

  convenient method for the one-pot synthesis of furans from β-keto esters and α-halo ketones was developed using an acid- and base-supported reagent system ‘Na2CO3/Al2O3-PPA/SiO2’. The condensation reaction of triketones, which are formed from the reaction of β-keto esters with α-halo ketones in the presence of Na2CO3/Al2O3, was promoted by PPA/SiO2 to give the corresponding furans in good yields. This method
