2,3-Functionalization of furans, benzofurans and thiophenes via magnesiation and sulfoxide-magnesium exchange.
The use of TMPMgCl.LiCl and iPrMgCl.LiCl allows a sequential 2,3-difunctionalization of various 2-arylsulfinyl furans, thiophenes and benzofurans. Subsequent use of the same reagents permits a selective full functionalization of all 4 positions of the furan and thiophene scaffolds.
