The enantiomerically pure N-C photoadducts, aminobutenolides 5a-5c have been obtained from the enantioselective photoaddition of secondary cyclicammes 4 with the chiral synthon 1 under the same conditions.展开更多

Only using stoichiometric amount of nano sized Mg(OH)_2,good to moderate isolated yields could be achieved in N-methylpyr-rolidone (NMP) after 24 h at 150℃.展开更多
