Phosphine Organocatalysis [PDF]
Chemical Reviews, 2018 The hallmark of nucleophilic phosphine catalysis is the initial nucleophilic addition of a phosphine to an electrophilic starting material, producing a reactive zwitterionic intermediate, generally under mild conditions. In this Review, we classify nucleophilic phosphine catalysis reactions in terms of their electrophilic components. In the majority of

Asymmetric Conjugate Hydrocyanation of α,β-Unsaturated Aldehydes Catalyzed by Engineered 2-Deoxy-D-ribose-5-phosphate Aldolase. [PDF]
ChemistryThe power of catalytic promiscuity: The enantioselective conjugate hydrocyanation of enals remains a long‐standing challenge for biocatalysis. Here, we report the redesign of 2‐deoxy‐D‐ribose‐5‐phosphate aldolase for the asymmetric conjugate hydrocyanation of aromatic enals, expanding the reaction scope of iminium‐based enzyme catalysis to include an ...
