Synthesis of S‐Arylthioxanthonium Trifluoromethanesulfonates From Thioxanthones and Diaryliodonium Salts by Copper(II) Catalysis and Application to Aryl–Heteroaryl Bond Formation by Direct LED Irradiation

European Journal of Organic Chemistry, EarlyView.
A straightforward Cu(II)‐catalyzed synthesis of S‐arylthioxanthonium trifluoromethanesulfonates from readily available thioxanthones and diaryliodonium salts is described. A broad range of salts is obtained in moderate to good yields. It is further demonstrated that S‐arylthioxanthonium trifluoromethanesulfonates act as aryl radical precursors under ...

Synthesis of S‐Linked Glycoconjugates of Monosaccharides and Levoglucosenone Derivatives Through Photoinduced Thiol–Ene Reaction Mediated by 4CzIPN and Its Water Soluble Analog

European Journal of Organic Chemistry, EarlyView.
Visible‐light thiol–ene reaction mediated by 4CzIPN enables access to hydrolytically stable S‐linked glycoconjugates from levoglucosenone‐derived thiols (Y = 91% to quant. d.r. = up to >95:5) and conventional thio‐sugars (Y = 80% to quant. d.r. = up to >95:5).

Unified Approach for the Synthesis of Close Analogues of Reverse‐Prenylated Hexahydropyrrolo Indole Alkaloids

European Journal of Organic Chemistry, EarlyView.
A simple, modular, and unified strategy for the synthesis of reverse‐prenylated hexahydropyrrolo indole alkaloids has been developed. An unusual retrosynthetic disconnection allows for the late introduction of a side chain, which distinguishes many members of this class of natural products.

Prepare, don't scare: Rethinking cognitive readiness before epilepsy surgery

Epilepsia Open, EarlyView.
Abstract Epilepsy surgery is an effective but underutilized treatment for drug‐resistant epilepsy, and concerns about postsurgical cognitive change are a prominent barrier. Refinements in surgical technique can reduce cognitive impact, but cognitive change cannot always be avoided, and approaches carrying lower cognitive risk are often less effective ...

Visitor‐I and dual worldmaking: Queer museology between Tuntenhaus and the Schwules Museum

Feminist Anthropology, EarlyView.
Abstract This article develops the visitor‐I as an embodied protocol for analyzing how queer archival exhibitions choreograph perception, affect, and learning, and it uses dual worldmaking as a bounded heuristic to name the relation between lived worldmaking in the Tuntenhaus squat and curatorial worldmaking in the museum, and I argue that the visitor ...
