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.

(Chemical Equation Presented) The combination of a molybdenum complex (CpMoCl(CO)3 or [CpMo(CO)3]2) and o-chloranil was used as a catalyst in the [3 + 3] cyclocoupling of phenols and allylic alcohols under microwave heating conditions. Substituted chromans were selectively obtained in moderate to good isolated yields.
