Kadir, Kamaliah published the artcilePurines, pyrimidines, and imidazoles. Part 56. Some aminoimidazolecarboxamidines and derived adenines, Formula: C10H11N3O3S, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1980), 2728-31, database is CAplus.
Cyclohexylimidazole I, prepared (37%) from H2NCH(CN)2, CH(OEt)3, and cyclohexylamine, gave 66% carboximidate II (R = OMe) on treatment with MeOH/HCl, which with NH3 gave 64% carboxamidine II (R = NH2) (III). Formylation of III gave N6-formyladenine IV (R = cyclohexyl), which was also prepared by formylation of 9-cyclohexyladenine. IV [R = CH2CH(OH)CH2OH] was similarly prepared The reaction of II (R = H) with HCO2H/Ac2O gave N6-formyladenine (IV; R = H), which was also prepared by formylation of adenine, whereas adenosine was not N-formylated under the same conditions.
Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) published new progress about 5098-14-6. 5098-14-6 belongs to nitriles-buliding-blocks, auxiliary class Nitrile,Salt,Sulfonic acid,Amine,Benzene, name is 2-Aminomalononitrile 4-methylbenzenesulfonate, and the molecular formula is C10H11N3O3S, Formula: C10H11N3O3S.
