Synergistic Catalysis with Azomethine Ylides

Chinese Journal of Chemistry, 2020
AbstractAzomethine ylides are useful intermediates for the rapid construction of chiral N‐containing compounds. However, its synthetic potential has not been fully developed due to the limited reaction models. In combination with synergistic catalysis and azomethine ylide chemistry, we have developed several types of novel catalytic system including Cu/

Enantioselective Cycloadditions of Azomethine Ylides

2008
The asymmetric 1,3-DCR of azomethine ylides, which is generated from the corresponding imino ester and alkenes, is one of the most fascinating transformations because the configuration of the four new stereogenic centers of the finally obtained proline can be absolutely established in only one step with total atom economy.

Microwave-Assisted [3 + 2] Cycloadditions of Azomethine Ylides

Organic Letters, 2003
The microwave-assisted intramolecular [3 + 2] cycloaddition reaction of azomethine ylides to activated and nonactivated alkenes and alkynes is described. The procedure allows the synthesis of pyrrolidines and pyrrole products in good to excellent overall yields in short reaction times.
