Journal ArticleDOI
Photosensitized, energy transfer-mediated organometallic catalysis through electronically excited nickel(II).
TL;DR: Here, excited-state organometallic catalysis via direct photoexcitation is demonstrated via such an activation pathway, and detailed mechanistic studies confirm the role of photosensitization via energy transfer.
Journal ArticleDOI
Advances in Stereoconvergent Catalysis from 2005 to 2015: Transition-Metal-Mediated Stereoablative Reactions, Dynamic Kinetic Resolutions, and Dynamic Kinetic Asymmetric Transformations
TL;DR: This Review summarizes major advances in nonenzymatic, transition-metal-promoted dynamic asymmetric transformations reported between 2005 and 2015.
Journal ArticleDOI
Enantioselective α-Alkylation of Aldehydes by Photoredox Organocatalysis: Rapid Access to Pharmacophore Fragments from β-Cyanoaldehydes
TL;DR: The combination of photoredox catalysis and enamine catalysis has enabled the development of an enantioselective α-cyanoalkylation of aldehydes, allowing rapid diversification of the oxonitrile products to a wide array of medicinally relevant derivatives and heterocycles.
Journal ArticleDOI
Radical philicity and its role in selective organic transformations
Faeze Parsaee,Milinda C. Senarathna,Prashansa B. Kannangara,Shevon N. Alexander,Phillip Damien E. Arche,Eric R. Welin +5 more
TL;DR: In this paper, the authors present a qualitative method to understand and predict radical philicity by classifying the typical reactivity of more than 30 types of radicals into nucleophilic or electrophilic behaviour.
Journal ArticleDOI
Concise total syntheses of (─)-jorunnamycin A and (─)-jorumycin enabled by asymmetric catalysis
Eric R. Welin,Aurapat Ngamnithiporn,Klatte Max,Guillaume Lapointe,Gerit Pototschnig,M McDermott,Dylan Conklin,Christopher D. Gilmore,Pamela M. Tadross,Christopher K. Haley,Kenji Negoro,Emil Glibstrup,Christian U. Grünanger,Kevin M. Allan,Scott C. Virgil,Dennis J. Slamon,Brian M. Stoltz +16 more
TL;DR: An approach to two bis-THIQ natural products, jorunnamycin A and jorumycin, that instead harnesses the power of modern transition-metal catalysis for the three major bond-forming events and proceeds with high efficiency, allowing for the preparation of a more diverse set of nonnatural analogs.
