The annulative coupling of secondary benzyl alcohols with internal alkynes efficiently proceeds in the presence of a silver catalyst. The reaction gives 1,2,3-substituted indene derivatives selectively as 1:1 coupling products. The procedure provides a straightforward synthetic route to indenes from readily available starting materials upon treatment with a simple reaction system under mild conditions.

A convenient and efficient method for the synthesis of polysubstituted indenes has been developed by the iron(III) trichloride-catalyzed tandem mono- and dibenzylation/cyclization reactions of benzylic alcohols with alkynes. This method is featured with the easily available starting materials, cheap catalyst, simple manipulation and mild conditions. Copyright
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.
