some organocatalyzed reactions proceeding with a high enantioselectivity. In our experimentation we found that the use of these compounds as the enolizable (nucleophilic) component in organocatalyzed Mannich-type reactions using in situ-generated cyclicN-acyliminiumions gave low diastereoselectivity and low to moderate values of enantioselectivity. This significant drop of facial selectivity with respect
