Front Cover: Rigid Multidimensional Alkoxyamines: A Versatile Building Block Library (Eur. J. Org. Chem. 2/2021)
Graphical Abstract
The Front Cover shows a broad selection of multidimensional alkoxyamines. In a versatile and scalable procedure, various substituted benzyl bromides have been generated as precursors. The graphic depicts the last reaction step, their transformation into the desired alkoxyamines assisted by copper and TEMPO. The exceptionally mild reaction conditions allowed reliable access to linear, trigonal planar, square planar and tetrahedral shaped alkoxyamines useful as organic building blocks. Involving an oxidation of copper, the reaction even allows for a quick and easy visual estimation of the conversion due to the evolution of a distinctive turquoise color.
