The field of oragnocatalysis has expanded tremendously over the last eighteen years and a
variety of highly functionalized compounds has been prepared.1 Organocatalytic
cyclization and cycloaddition2
reactions play an important role for the synthesis of
carbocyclic and heterocyclic frame works. Besides, monoactivation by organocatalysts,
dual activation of both electrophile and nucleophile have also been found to be essential
for obtaining high enantioselectivities.
Our group is interested for the development of new organocatalytic cyclization reactions.
The presentation will include organocatalytic enamine, iminium mediated reactions as
well as bifunctional amino thiourea/squaramide catalysed reactions.
