| N4-Acetylcytosine Usage And Synthesis |
| Chemical Properties | Crstalline powder | | Uses | N4-Acetylcytosine may be used in the preparation of cytidine. It may be used in the preparation of 1-(4-azido-4-deoxy-β-D-glucopyranosyl)cytosine. | | General Description | Four stable conformers of N4-acetylcytosine, and the one of the stable form containing an intramoleuclar six-membered ring have been reported by theoretical calculations.The infrared and FT-Raman spectra of N4-acetylcytosine in the solid phase has been reported. | | Purification Methods | If TLC or paper chromatography shows that it contains unacetylated cytosine, then reflux it in Ac2O for 4hours, cool at 3-4o for a few days, collect the crystals, wash them with cold H2O, then EtOH and dry at 100o. It is insoluble in EtOH and dissolves in H2O with difficulty, but crystallises in prisms from hot H2O. It is hydrolysed by 80% aqueous AcOH at 100o/1hour. [UV: Brown et al. J Chem Soc 2384 1956, Codington et al. J Am Chem Soc 80 5164 1958.] It forms an Hg salt [Fox et al. J Am Chem Soc 79 5060 1957]. [Beilstein 25 III/IV 3657.] |
