Hirota, Kosaku published the artcileNovel and efficient synthesis of 8-oxoadenine derivatives, Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate, the publication is Heterocycles (2001), 55(12), 2279-2282, database is CAplus.
A novel synthetic method for the preparation of 8-oxoadenine derivatives was reported. This widely applicable synthetic method was realized through the use of 5-amino-2,3-dihydro-2-oxo-1-(phenylmethyl)-1H-imidazole-4-carbonitrile as the key intermediates. A variety of substituents were successfully introduced to the 2- and 9-position of the 8-oxoadenine nucleus.
Heterocycles 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, Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate.
