Connecting hindered amines with aminoxyl radicals. I. One-step synthesis of spin-labelled esters.
This paper introduces a one-step procedure of general use for obtaining spin-labeled esters. The method implies base-catalyzed transesterification of methyl esters of fatty acids, aromatic acids, hydroxyaromatic acids, unsaturated acids, etc. with paramagnetic alcohols (e.g. 1-3) resulting in a vast array of new and known aminoxyl esters.
