Highly efficient synthesis of polysubstituted fluorene via iron-catalyzed intramolecular Friedel-Crafts alkylation of biaryl alcohols

An efficient and mild Fe(III)-catalyzed intramolecular Friedel-Crafts alkylation of biaryl methanol derivatives has been developed to achieve the substituted fluorene derivatives. The present reaction provides an excellent alternative to published methods

Reactions of α-Oxoketenedithioacetals with Phenylmagnesium Bromide: Synhesis of Novel 1-Phenyl-1-methylthio-3-phenyl (or 2,3-Fused)-indenes and 2,3-Fused Heterocyclic-1,3-Diphenyl-2-alken-1-ones

Novel substituted and 1-methylthio-1-phenylindenes have been synthesised by boron trifluoride etherate cyclocondensations of the corresponding carbinol acetals obtained by sequential 1,4 and 1,2 additions of phenylmagnesium bromide to α-oxoketenedithioacetals.Some of these indenes have been desulphurized to give the parent ring systems.Synthesis of novel 2,3-fused heterocyclic 1,3-diphenyl-alken-1-ones by boron trifluoride-ether catalyzed methanolysis of the corresponding carbinol acetals has also been described.
