Synthesis of new 2-mono- and 2,5-di-functionalized pyrrolidin-1-oxyl spin labels
Abstract
The preparation of new 2-mono-[type (3)] and 2,5-di-functionalized [type (4)] pyrrolidin-1-oxyl spin labels is described. For the formation of the functional groups (X = OH, CHO, CO2H, Br), methods previously unused in nitroxide synthesis are applied.
