A new approach to the synthesis of 1,3-dimethyl-4,5-disubstituted imidazolidin-2-ones
摘要:
1, 3 -Dimethyl-4,5-di(ureido)-substituted imidazolidin-2-ones have been synthesised by the nitrosation of 1,3-dimethyl-4,5-di(3-ethylureido)imidazolidin-2-one followed by the reactions of amines with the resulting 1,3-dimethyl-4,5-di(3-nitroso3-ethylureido)imidazolidin-2-one, and the structure of 1,3-dimethyl-4,5-di(3-ethylureido)imidazolidin-2-one has been confirmed by X-ray diffraction analysis.
