Multifunctional Asymmetric Catalysis.
Chemical 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 ...

A unified machine-learning protocol for asymmetric catalysis as a proof of concept demonstration using asymmetric hydrogenation. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Development of suitable machine-learning (ML) approaches by using molecular descriptors can provide significant impetus to current efforts in asymmetric catalysis, wherein one strives to make a desired stereoisomer of a given handedness ...

Asymmetric 1,4-functionalization of 1,3-enynes via dual photoredox and chromium catalysis
Nature Communications, 2022 In contrast to the better-studied ionic pathway, radical-involved asymmetric 1,4-functionalization of 1,3-enynes remains a prominent challenge. Here, the authors describe the asymmetric three-component 1,4-dialkylation of 1,3-enynes via dual photoredox ...
