Methyl2-(4-methoxybenzoyl)-3-(4-methoxyphenyl)-3-oxopropanoylcarbamate 1 which is a new P-tricarbonyl compound reacted with some aromatic hydrazines 2a-f and amino acids-esters 5a-d to give oxopropanohydrazides 3a-b and pyrazolones 4c-f the together with oxopropanoyl-amino acids-esters 6a-d. These new compounds were obtained in moderate to excellent yields (48-78%). The structures of all new synthesized compounds were determined with the H-1 and C-13 NMR,IR spectroscopic data and elemental analyses. Most of them were compared with their previously obtained analogues.
