An efficient aminocatalytic enantioselective Michael addition of readily available cyclic hemiacetals to nitroolefins has been developed. The strategy serves as a powerful approach to synthetically valuable chiral 3-substituted tetrahydrofurans (THFs) I [R = Et, Ph, 3-NO2-C6H4, etc.] and tetrahydropyrans (THPs) II. The synthetic utilities of the versatile Michael adducts also have been demonstrated in the synthesis of 2,3-disubstituted cyclic ethers, α-substituted lactones and venlafaxine analogs.
