Catalysing (organo-)catalysis: Trends in the application of machine learning to enantioselective organocatalysis

Beilstein Journal of Organic Chemistry
Organocatalysis has established itself as a third pillar of homogeneous catalysis, besides transition metal catalysis and biocatalysis, as its use for enantioselective reactions has gathered significant interest over the last decades.

Enantioselective Conjugate Addition of Malononitriles to Enynes: A Stereodivergent Approach to Chiral Allenes

European Journal of Organic Chemistry, EarlyView.
Quinine‐catalyzed enantioselective conjugate addition of malononitrile derivatives to enynes provides trisubstituted chiral allenes in good to excellent yields and high enantiopurities under mild conditions. Broad substrate scope, easy scalability, and versatile post‐synthetic transformations into enantioenriched pyrazoles and furans highlight the ...
