Abstract
Synthesis of spin labelled chromone 4a is described from paramagnetic acid derivatives la, Ib by the conventional Baker-Venkataraman procedure. Differ ent hydroxylated paramagnetic chromone derivatives 8, 9, 12a, and 126 could be obtained by different one-pot reactions and a glycoside of 5-dihyroxy-2 -(1-oxyl-2,5-dihydro-2,2,5,5-tetramethyl-1H-pyrrol-3-yl) chromone radical 1 4b was synthesized.
