A convenient and straightforward strategy for the synthesis of 2,3-disubstituted and 2,3,5-trisubstituted furans via a base-promoted domino reaction of β-keto compounds with vinyl dichlorides is described. This transition-metal-free approach proceeds under operationally simple reaction conditions featuring easily available starting materials, a broad substrate scope, and good functional group tolerance.

A convenient method for the one-pot synthesis of furans from -keto esters and -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 -keto esters with -halo ketones in the presence of Na2CO 3/Al2O3, was promoted by PPA/SiO2 to give the corresponding furans in good yields. This method is simple and easy to perform in comparison with stepwise processes, and the yields are good.

A novel cyclization process of 2,3-bis(trimethylsilyl)buta-1,3-diene with various acyl chlorides in the presence of aluminium trichloride affords 2,5-disubstituted or 2,3,5-trisubstituted furans in short reaction time; a subsequent acylation process of th
