Multifunctional Asymmetric Catalysis.

open access: yesChemical and Pharmaceutical Bulletin, 2001
Two types of general and practical enantioselective catalysts, namely, bimetallic complexes and Lewis acid-Lewis base bifunctional catalysts were developed based on the concept of multifunctional catalysis. In the first part of this review, the first example of a catalytic enatioselective nitro-Mannich reaction as well as a direct catalytic ...
