摘要：The asymmetric intramolecular oxa-Michael reactions of alpha,beta-unsaturated ketones have been achieved by using readily accessible primary-secondary diamines as the organocatalysts, giving the synthetically useful tetrahydrofurans/2H-pyrans in good yields and with high enantioselectivities (up to 90% ee).
