WebStrain-promoted alkyne-nitrone cycloadditions (SPANC) represent rapid, efficient, selective, and tunable conjugation strategies that are applicable to biomolecular labelling … WebThe SPAAC vs SpANC reaction. Because this reaction is metal-free and proceeds with fast kinetics (k2 as fast as 60 1/Ms, faster than both the CuAAC or the SPAAC) SPANC can be used for live cell labeling. Moreover, substitution on both the carbon and nitrogen atoms of the nitrone dipole, and acyclic and endocyclic nitrones are all tolerated. ... WebSPANC reaction and their reactivity has been described.34 Similarly, a rearrangement of the product can occur in the case of CMPO nitrone used with a terminal alkyne in the copper-catalyzed reaction (CuANCR).32 Therefore, further reactions based on the nitrone group are warranted with more stable and more reactive nitrone dipoles to be ... orion panelbeaters \\u0026 spraypainters
