Michael addition of 5-aryl-l, 3-cyclohexanedione to the chalcones was carried out in the acidic or basic condition to give the corresponding cis- and trans-2,4,7-triaryl-5-oxo-4#-5,6,7,8- tetrahydrobenzopyrans bearing two chiral atoms. The structures and configurations of the products were confirmed by elemental analysis, IR, 'H NMR and NOE, and the reaction mechanism was discussed as well.
