Lewis acid-catalyzed tandem synthesis of 9-sulfonylamino- and 9-arylfluorenes

A Lewis acid-catalyzed three-step tandem synthesis of 9-arylfluorene was developed by simply heating a mixture of 2-formyl biphenyl, TsNCO and an arene. In the absence of arene, a two-step tandem synthesis of 9-sulfonylaminofluorene was achieved. These ad

Facile Cu(OTf)2-catalyzed preparation of 9-tosylaminofluorene derivatives from o-arylated N-tosylbenzaldimines

The 9-tosylaminofluorene derivatives were synthesized conveniently by Cu(OTf)2-catalyzed aza-Friedel-Crafts reaction of o-arylated N-tosylbenzaldimines in high yields. This is an efficient, atom-economic, and green method.

Efficient synthesis of 9-tosylaminofluorene derivatives by boron trifluoride etherate-catalyzed aza-friedel-crafts reaction of in situ generated N-tosylbenzaldimines

An efficient and expeditious boron trifluoride etherate (BF 3·Et2O) catalyzed one-pot reaction for the synthesis of N-tosyl-9-aminofluorenes and anthracene derivatives from in situ generated N-tosylbenzaldimines via an aza-Friedal-Crafts reaction has been developed. The catalytic reaction shows high substrate tolerance with excellent yields.
