Synergistic Catalysis with Azomethine Ylides
Chinese Journal of Chemistry, 2020AbstractAzomethine 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/

Following the generation of azomethine ylide 3 from the β-lactam-based oxazolidinone 1, a series of alternative entries to this and related 1,3-dipoles have been explored. The first approach is based on the use of monocyclic azetidinones 6–12 and 14 carrying a leaving group at C(4) and an activated (acidic) proton adjacent to the ring nitrogen ...

Synthesis and Use of a Trifluoromethylated Azomethine Ylide Precursor
The Journal of Organic Chemistry, 2012The presence of fluorous substituents can impart a dramatic effect on the efficacy of molecules used for a range of applications in society. Here, we describe the preparation and use of a new trifluoromethylated azomethine ylide precursor, which leads to a series of fluorinated pyrrolidine, 3-pyrroline, and pyrrole building blocks.

Enantioselective Cycloadditions of Azomethine Ylides
2008The 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.
