The novel fluorous organocatalyst bearing a diaminomethylenemalononitrile motif is prepared. The fluorous organocatalyst efficiently promotes asymmetric conjugate additions of ketones to nitroalkenes and results in high yields of these addition products with excellent enantioselectivities under solvent-free conditions.

experimental part, p. 1171 - 1177 (2011/03/22)
A simple and convenient strategy was developed to synthesize a new class of pyrrolidinyl-camphor based bifunctional organocatalysts possessing varying functional linkers. Catalytic screening of these camphor-pyrrolidine linked derivatives for asymmetric M
