functionalized water-soluble azobenzene reagent (BSBDA) and its application as a new tool for the rapid generation of visible light-responsive macrocyclic peptides and peptide libraries displayed on the surface of bacteriophage. The allenamide functionality promotes cysteine ligation in model peptides and those displayed on phage with rates 2–3 orders of magnitude faster than the established alkyl halide

Bruton'styrosinekinase (BTK) inhibitors such as ibrutinib hold a prominent role in the treatment of B cell malignancies. However, further refinement is needed to this class of agents, particularly in terms of adverse events (potentially driven by kinase promiscuity), which preclude their evaluation in nononcology indications. Here, we report the discovery and preclinical characterization of evobrutinib
A new method for the smooth and highly efficient preparation of polyalkylated aryl propiolates has been developed. It is based on the formation of the corresponding aryl carbonochloridates (cf. Scheme 1 and Table 1) that react with sodium (or lithium) propiolate in THF at 25 – 65°, with intermediate generation of the mixed anhydrides of the arylcarbonic acids and prop-2-ynoic acid, which then decompose
