Synthesis of pyrrolidines and pyrrolidinones by the rhodium complex catalyzed cyclization of unsaturated amines
摘要:
N-Allylic arylamines react with carbon monoxide, sodium borohydride, 2-propanol, and catalytic amounts of the zwitterionic complex eta-6-C6H6BPh3-Rh(COD)+ (1), to form pyrrolidines as the main products in most cases. Pyrrolidinones result from N-allylic alkylamines. An alternate route to the lactams from N-allylic alkylamines involves synthesis gas instead of CO/NaBH4, together with the dual catalytic system 1/[Ru(CO)3Cl2]2. Complementary to the N-allylic arylamine route to pyrrolidines with NaBH4 and 1 is the use of synthesis gas, 1, and 1,4-bis(diphenylphosphino)butane.

The present invention refers to new classes of polymerisable monomers, to molecularly imprinted polymers obtainable by polymerisation of at least one of the monomers and a crosslinking monomer in the presence of a template molecule. The obtained polymers may be used for separation of enantiomers, diastereomers of the template molecule, and also for separation of the template molecule or template molecule analogues from structurally related compounds.
