InIII-catalysed tandem C-C and C-O bond formation between phenols and allylic acetates

Indium triflate catalysed tandem allylation-intramolecular hydroalkoxylation was efficiently carried out by using 1 mol-% of the catalyst under mild conditions to afford the dihydrobenzopyran ring system (chroman-type structure) in good yields. Kinetic, mechanistic and theoretical studies are also presented. Tandem allylation-intramolecular hydroalkoxylation carried out in the presence of an indium catalyst (1 mol-%) under mild conditions provides the dihydrobenzopyranring system in good yields. Kinetic, mechanistic and theoretical studies are presented.
