    Synthesis of new substituted 5-methyl-3,5-diphenylimidazolidine-2,4-diones from substituted 1-(1-cyanoethyl-1-phenyl)-3-phenylureas

  • Original language description

    The reaction of substituted phenyl isocyanates with 2-amino-2-phenylpropanenitrile and 2-amino-2-(4-nitrophenyl)propanenitrile has been used to prepare substituted 1-(1-cyanoethyl-1-phenyl)-3-phenylureas. In anhydrous phosphoric acid the first products to be formed from 1-(1-cyanoethyl-1-phenyl)-3-phenylureas are phosphates of 4-methyl-4-phenyl-2-phenylimino-5-imino-4,5-dihydro-1,3-oxazoles, which on subsequent hydrolysis give the respective ureidocarboxylic acids. On prolongation of the reaction time,the phosphates of 4-methyl-4-phenyl-2-phenylimino-5-imino-4,5-dihydro-1,3-oxazoles rearrange to give phosphates of 5-methyl-4-imino-3,5-diphenylimidazolidin-2-ones, and these are subsequently hydrolysed to the respective substituted 5-methyl-3,5-diphenylimidazolidin-2,4-diones. The ureidocarboxylic acids were also prepared by alkaline hydrolysis of 5-methyl-3,5-diphenylimidazolidin-2,4-diones. The 5-methyl-3,5-diphenylimidazolidin-2,4-diones and ureidocarboxylic acids were characterised

    Syntéza nových substituovaných 5-methyl-3,5-difenylimidazolidin-2,4-dionů ze substituovaných 1-(1-kyanethyl-1-fenyl)-3-phenylmočovin

  • Czech description

    Reakcí substituovaných fenylisokyanátů s 2-amino-2-fenylpropannitrilem a 2-amino-2-(4-nitrofenyl)propannitrilem byly připraveny substituované 1-(1-fenyl-1-kyanethyl)-3-fenylmočoviny. V bezvodé kyselině fosforečné nejprve vznikají z 1-(1-fenyl-1-kyanethyl)-3-fenylmočovin fosfáty 4-fenyl-4-methyl-2-fenylimino-5-imino-4,5-dihydro-1,3-oxazolů, které následnou hydrolýzou poskytují příslušné ureidokarboxylové kyseliny. Prodloužením reakční doby dochází k přesmyku fosfátů 4-fenyl-4-methyl-2-fenylimino-5-imino-4,5-dihydro-1,3-oxazolů za vzniku fosfátů 5-methyl-4-imino-3,5-difenylimidazolidin-2-onů, které následně hydrolýzou poskytují odpovídající substituované 5-methyl-3,5-difenylimidazolidin-2,4-diony. Ureidokarboxylové kyseliny byly rovněž připraveny alkalickou hydrolýzou 5-methyl-3,5-difenylimidazolidin-2,4-dionů. 5-Methyl-3,5-difenylimidazolidin-2,4-diony a ureidokarboxylové kyseliny byly charakterizovány pomocí 1H, 13C NMR spektroskopie.
