tandem Mannich-Michael reaction with Danishefsky'sdiene in the presence of Lewis acids. The temperature, catalyst and solvent dependence of the product ratio is described. Under zinc iodide-catalysed conditions in acetonitrile at −20°C, double stereodifferentiation using (R)-2,3-di-O-benzylglyceraldehyde (S)-N-α-(methylbenzyl)imine as starting material was successful and the reaction occurred with good
