• 論文の詳細を見る

• Cyclization of <I>N</I>,<I>N</I>′-[<I>N</I>-(benzyloxycarbonyl) (Z)-iminobis(methylenecarbonyl)]bis[glycine] dimethyl ester to the hydantoin derivative took place easily under mild ammonolysis conditions. Replacement of Z by <I>p</I>-methoxy-benzyloxycarbonyl also led to the cyclization. Influence of different substituent groups on the cyclization was studied with some <I>N</I>-Z-dipeptide methyl esters.
