Reaktionsschritte
ADAC, 2 (11.8 mg, 20 umol), was suspended in 0.5 ml DMF and treated with 4-isothiocyanato-TEMPO (2,2,6,6,-tetramethyl-1-piperidinyloxy, free radical (7 mg, Aldrich). After 1 hour 1.5 ml water was added to the solution, and the precipitate was collected, washed with a minimum of MeOH and ether, and recrystallized from DMF/ether/petroleum ether, to give a product which was homogeneous by thin layer chromatography and gave proton NMR and ESR spectra consistent with the structure. Yield 8.3 mg (51%). Cf-MS peak at 758 (m+1-MeO) and 626 (m+1 -ribose). IR shows a peak at 1580 cm-1, characteristic of a thiourea carbonyl stretch.
