5-Aryl-2-furaldehydes, obtained by furfural arylation with arenediazonium salts, react with ethyl acetoacetate or acetylacetone and (thio)- urea in the presence of FeCl3·6H2O as a catalyst. A series of ethyl 4-(5-aryl-2-furyl)-6-methyl-2-oxo(thioxo)-1,2,3,4-tetrahydropyrimidine- 5-carboxylates was obtained.

Three-component condensation of naphthalen-2-amine with 5-arylfuran(thiophene, N-methylpyrrole)-2-carbaldehyde and 5,5- dimethylcyclohexane-1,3-dione, as well as condensation of N-[(5- arylfuran(thiophen)-2-ylmethylidene]naphthalen-2-amine with 5,5- dimethylcyclohexane-1,3-dione gave the corresponding 12-[5-arylfuran(thiophen, N-methylpyrrol)-2-yl]-7,8,9,10-tetradrobenzo[a]acridin-11(12H)-ones.

experimental part, p. 1145 - 1148 (2009/04/06)
A simple and effective method has been elaborated for the synthesis of thieno[2,3-b]indole ring system. It is based on the electrophilic recyclization of 2-alkyl-5-(2-isothiocyanoaryl)furans in the presence of anhydrous AlCl 3. Georg Thieme Ver
Furan as a 1,3-diketone equivalent: the second type furan recyclization applied to indole synthesis
Butin, Alexander V.
, p. 4113 - 4116 (2007/10/03)
A new approach for the synthesis of indole derivatives based on protolytic recyclization of 2-alkyl-5-(2-tosylaminoaryl)-furans is described. The furan ring in this unusual transformation formally serves as a 1,3-diketone equivalent.
