A heterogeneous enantioselective oxa-Michael-Michael reaction for the synthesis of chromans has been developed on a heterogeneous acid-base synergic catalyst with inherent silica as acidic sites and immobilized chiral amines as basic sites. Final products were afforded in selectivity of up to 98% and ee of 97% from 2-nitrovinyl phenol and 3-methyl-2-butenal. The heterogeneous synergistic catalytic mechanism has also been studied.
