In the latter approach, acid-base interactions in the substrate-catalyst complex will lead to a significant bathochromic absorption shift of the substrate, enabling a selective excitation within the complex and a subsequent enantioselective reaction
pathway within a spatially defined chiral environment.
The enantioselective reaction
was tested for success using HPLC-MS, with negative results.
Copper-Bis(oxazoline) Catalyzed Synthesis of (beta)s - Enantioselective Reaction
of Alkynes with Nitrones (David A.
17) It should be clearly noted, however, that none of these enantioselective reactions
directly involves C-C bond formation.
Chemists introduce enantioselective reactions
promoted by copper and the variety of solutions for many reaction types involving copper catalysis.
Other chapters look at a wide range of topics related to polymers, the longest examining nitrogen-containing ligands anchored onto polymers as a catalyst stabilizer for catalytic enantioselective reactions
