Phase selectively soluble dendritic derivative of 4-(N,N-dimethylamino)pyridine: an easily recyclable catalyst for Baylis-Hillman reactions

A new type of soluble, alkyl-modified dendritic DMAP was synthesized, and successfully applied in the thermomorphic binary system (DMF/cyclohexane, 1/1, v/v) for Baylis-Hillman reaction, and the dendritic catalyst could be easily recycled by changing the temperature of the system.
