Synthesis of spin labelled chromone 4a is described from paramagnetic acid derivatives 1a, 1b by the conventional Baker-Venkataraman procedure. Different hydroxylated paramagnetic chromone derivatives 8, 9, 12a, and 12b could be obtained by different one-pot reactions and a glycoside of 5-hydroxy-2-(1-oxyl-2,5-dihydro-2,2,5,5-tetramethyl-1H-pyrrol-3-yl) chromone radical 14b was synthesized.
