Abstract: A range of nanoporous aluminosilicates varying in their aluminium content were synthesised using an evaporation-induced self-assembly (EISA) approach under acidic conditions. The nanoporous materials produced display narrow pore size distributions and the expected large BET surface areas. The activity and selectivity of these materials to function as Lewis acid catalysts for the addition of alcohols to styrene oxide and cyclohexene oxide were assessed and found to be optimum using high aluminium containing materials. © 2009 Elsevier B.V.

Tomasz M. Kubczyk,Sarah M. Williams,Jacqueline R. Kean,Thomas E. Davies,Stuart Hamilton Taylor,Andrew E. Graham +5 more
TL;DR: In this article, a tandem Friedel-Crafts protocol was proposed for the synthesis of bisindolylalkane products using aldehydes and acetal reagents, where the acetal is generated in situ and undergoes subsequent reaction.

TL;DR: In this article, the authors report a novel strategy for the efficient synthesis of levulinate esters from levulinic acid in the presence of trialkyl orthoformates or dialkyl acetals and ketals catalyzed by commercial catalysts, such as ZSM-5 and Amberlyst-15.
Indium(III) triflate promoted synthesis of alkyl levulinates from furyl alcohols and furyl aldehydes

Metal triflate catalysed acetal exchange reactions of glycerol under solvent-free conditions
TL;DR: In this article, a transacetalisation protocol for glycerol with acyclic acetals was proposed. But the protocol is restricted to solvent-free reaction conditions. And it requires very mild reaction conditions, such as acetophenone or benzophenone.
