  Enantiomerically pure guanidine-catalysed asymmetric nitroaldol reaction

  摘要：

  Enantiomerically pure guanidines with and without C-2 symmetry have been prepared and used as catalysts in the addition of nitromethane to aldehydes (Henry reaction). The influence of the structure and amount of the guanidine, the solvent and the temperature in the enantioselectivity of the nitroaldol reaction has also been studied.
