An efficient method has been developed for the cascade synthesis of azo[l,2-a]indolones from azoles and 2-fluoroaldehydes based on an iron-catalyzed SNAr and a direct acylation reaction. A number of azo[l,2-a]indolones containing different azole rings and substituents were obtained in good yields.An efficient method has been developed for the cascade synthesis of azo[l,2-a]indolones from azoles and 2-fluoroaldehydes based on an iron-catalyzed SNAr and a direct acylation reaction.

ABSTRACT

FeCl₃-catalyzed cross-coupling of o-iodobenzoic acids with azole-2-thiols and amidation followed by in situ acidic condensation delivered azo[2,1-b][1,3]-benzothiazinones. A simple “one-pot” operation is conducted for this reaction. This reaction avoids the use of expensive catalytic reagents and provides the desired products containing different azole rings and substituents in good yields.
