Flavin Catalysts in Organic Synthesis
Angewandte Chemie, EarlyView.Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

N‐Alkoxysulfurdiimide Reagents for the One‐Step Modular Synthesis of Primary Sulfonimidamides
Angewandte Chemie, EarlyView.N‐Alkoxysulfurdiimide reagents when combined with organometallic reagents lead directly to primary sulfonimidamide products. The reactions are broad in scope, encompassing aryl, heteroaryl, and alkyl carbon substituents. The reactivity of the N‐alkoxysulfurdiimide reagents can be correlated with the electron‐withdrawing ability of the N‐substituent ...
