AgONO-Assisted Direct C-H Arylation of Heteroarenes with Anilines
A novel copper-catalyzed C-H arylation of heteroarenes with anilines by an in situ diazonium reaction is established by using silver nitrite (AgONO) as an unconventional nitrosating reagent under acid-free conditions. It provides a complementary approach for the C-H arylation of electron-rich heteroarenes with aromatic amines affording a variety of heterobiaryls in moderate to good yields.

Palladium-catalyzed decarboxylative C-H bond arylation of furans
A Pd/PCy3/Ag2CO3 (Cy = cyclohexyl) catalytic system was found to promote decarboxylative arylation through the combination of decarboxylation and C-H bond functionalization. This protocol features a good substrate scope of

Furan ring opening-indole ring closure: Recyclization of 2-(2-aminophenyl)furans into 2-(2-oxoalkyl)indoles
The acid-catalyzed rearrangement of 5-alkyl-2-[2-(sulfonylamino)phenyl] furans into 2-(2-oxoalkyl)indoles is described. When the N-sulfonyl group in the starting compounds was displaced by an N-acyl group, the corresponding indoles were not formed under t

A new simple route to the thieno[2,3-b]indole ring system
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
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.
