Popis:	1. A general method has been developed for the preparation in good yield on N-benzoylated imidazolidone derivatives by the Curtius reaction, which is applied to esters of N-benzoylated β-amino acids. 2. The reaction has been carried out with N-benzoyl-β-phenyl-β-alanine, N-benzoyl-β-(m-nitrophenyl)-β-alanine, and N-benzoyl-β-piperonyl-β-alanine. 3. It has been found that reaction of excess of hydrazine hydrate with N-benzoyl-β-(m-nitrophenyl)-β-alanine yields the hydrazide of β-(m-aminoplienyl)-N-benzoryl-β-alaniiie, i.e., reaction is accompanied by reduction of the Witro group.
