Designing the First Hydroxylamine Substituted Tetrazole With N,O‐Dimethylhydroxylamine
Despite decades of tetrazole chemistry, hydroxylamine‐substituted variants have remained unknown. This work reports the first synthesis of a 5‐hydroxylamine substituted tetrazole via cyanogen azide and N,O‐dimethylhydroxylamine, yielding the free‐base compound and its hydrochloride salt.

Structural and biochemical basis for retinol‐binding protein 4 antagonism by tinlarebant
Background and Purpose Retinol‐binding protein 4 (RBP4) is a member of the lipocalin superfamily that is connected to disease states such as insulin resistance, fatty liver disease and ocular disorders including Stargardt disease. Several retinoid and non‐retinoid antagonists of this protein have been developed for potential clinical use, but none have

One‐pot gold(I)‐catalysts synthesis was developed in order to prepare N‐alkenyl 2‐pyridonyl azides. This method provides a series of N‐alkenyl 2‐pyridonyl azides in moderate to excellent yields (up to 94%). ABSTRACT A novel strategy, involving the preparation of gold‐catalyzed cyclization salts and the rearrangement of these salts in the presence of ...
