A one-pot, highly diastereoselective synthesis of chroman derivatives with three contiguous stereogenic centers is described. In this reaction, three transformations (iminium formation/Morita-Baylis-Hillman reaction/oxa-Michael reaction) occurred successively to afford multisubstituted chroman derivatives in moderate chemical yields with excellent diastereoselectivities (d.r. = 20:1:1:1).
