The invention provides certain bis-acylated hydroxylamine derivative compounds, pharmaceutical compositions and kits comprising such compounds, and methods of using such compounds or pharmaceutical compositions. In particular, the invention provides methods of using such compounds or pharmaceutical compositions for treating, preventing, or delaying the onset and/or develop of a disease or condition. In some embodiments, the disease or condition is selected from cardiovascular diseases, ischemia, reperfusion injury, cancerous disease, pulmonary hypertension and conditions responsive to nitroxyl therapy.
products, and biologically active compounds showcase the robustness and functional‐group tolerance of the reaction. The key to the success of the reaction could be the possible formation of the strong Si−O bond via a Brook‐type rearrangement. Given its simplicity and efficiency, this ligation has the potential to unfold new applications in the areas of medicinal chemistry and chemical biology.

A new prosthetic group is reported for 18F-labelling of peptides and proteins based on the chemoselective ligation of potassium acyltrifluoroborates (KATs) and hydroxylamines without any detectable 18F/19F isotope exchange at the acyltrifluoroborate moiety. The new building block is appended via a common amide bond at room temperature with no need for protecting groups which enables an effective orthogonal

New bifunctional potassium acyltrifluoroborate (KAT) substrates have been synthesized in gram scale using optimized reaction conditions. Chemoselective transformation of functional groups in the presence of an acyltrifluoroborate has been demonstrated, and orthogonalreactions of bifunctional KAT reagents are reported. This allows for the incorporation of KAT moieties into peptides and dyes.

the synthesis of monomers for atom‐transfer radical polymerization (ATRP) and a reversible addition‐fragmentation chain transfer (RAFT) agent bearing trifluoroborate iminiums (TIMs), which are quantitatively converted into potassium acyltrifluoroborates (KATs) after polymerization. The resulting KAT‐containingpolymers are suitable for rapid amide‐forming ligations for both post‐polymerization modification
