Johnson, Francis,Subramanian, Raghupathi

, p. 5040 - 5041 (1986)

A new base-induced cyclization is described which involves the direct one-pot conversion of trifluoroethyl phenyl ethers, thioethers, and amines, in the presence of 4 equiv of alkyl- or aryllithium reagents, to 2,3-disubstituted benzofurans, thianaphthene
