Aiming at preparation of biologically active compounds a bromination of N,N'-substituted malonodiamides in a glacial acetic acid was carried out. The use of one equiv of bromine provided mono-bromo derivatives, with two equiv of bromine dibromo-substituted products were obtained. Among the N,N'-dibenzylantides of alkylmalonic acids only the methyl homolog underwent bromination. The structure of compounds was proved by IR and H-1 NMR spectroscopy. The effect of the compounds synthesized on the central nervous system was investigated.

A new method for the synthesis of previously unknown ethyl 2-amino-1-(aryl)-5-(arylcarbamoyl)-6-oxo-1,6-dihydropyridine-3-carboxylates by a reaction of ethyl2-cyano-3-ethoxyacrylate with N1,N3-diarylmalonamides was developed. The antibacterial activity of some of the synthesized compounds was assayed.

By condensation of symmetrical malonic acid diamides with dichloromethane (method a) and with paraform (method b) N,N',N",N"'-substituted amides of 1,1,3,3-propanetetracarboxylic acid were synthesized. Better yields of the target products (68-80%) and the use of less toxic reagents indicate that method b is more feasible. The primary pharmacological screening revealed that the compounds obtained possess pronounced anticonvulsant activity at moderate toxicity.
