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.

Difluoromethylenation of Alkynes: Streamlined Access to Allyl Difluorides
Angewandte Chemie, EarlyView.Stabilizing primary oxocarbenium in HF/pyridine unlocks a direct alkyne difluoromethylenation – an efficient route to synthetically‐relevant allyl difluorides in a single step. ABSTRACT A direct difluoromethylenation of alkynes has been developed using HF/pyridine as a dual acidic and fluorinating medium. The reaction proceeds via in situ generation of

Angewandte Chemie, EarlyView.Catalytic, intramolecular N‐heterocycle arylation by nucleophilic aromatic substitution (SNAr) is now available for synthesis of highly strained macrocycles and medium‐sized heterobiaryl atropisomeric rings, including atropopeptides. Key to the approach is the ability to generate a strong base catalytically, taking advantage of base‐embedding ...
