A synthesis method has been developed and a number of new 2-aminochalcones have been obtained, conditions have been selected for the preparation of 5-styryl-1,2-dihydro-1,4-benzodiazepines on their basis. The synthesis of new 3-phthalimidoacyl-1,4-benzodiazepin-2-ones has been carried out. Condensation of 3-chloro-1,4-benzodiazepin-2-ones with o-, m-, p-fluoro, or o-, m-, p-chloroanilines synthesized a series of 3-chlorophenyl- and 3-(fluorophenyl)amino-1,4-benzodiazepin-2-ones. A synthesis method was proposed for obtaining the previously described series of 5-[(E)-2-(4-phenylvinyl)]-1,2-dihydro-3H-1,4-benzodiazepin-2-ones. Condensation of benzophenone, adamantanone or fluarenone with 7-bromo-5-phenyl-1,4-benzodiazepin-2-one has been carried out. It is shown that the best yields of the target products are obtained when using cesium carbonate as a base. Optically active 3-alkyl-5-[(E) -2 (aryl)vinyl]-1,2-dihydro-3H-1,4-benzodiazepin-2-ones have been synthesized. A number of new 1,4-benzdiazepin-2-ones containing piperazine benzoic acid residues at position 3 have been synthesized. Using the immobilized microsomal fraction, enantioselective hydrolysis of 3-acetoxy-7-bromo-5-phenyl-1,4-benzodiazepin-2-one was carried out and the S-enantiomer of the substrate was obtained. The affinity of 3-phthalimidoacyl 1,4-benzodiazepin-2-ones to the BDR of the central nervous system was studied and it was found that compounds of this series have a high affinity. When studying the effect of 1,4-benzodiazepine derivatives on the appetite of rats using the "Anorexia" method, it was shown that some compounds exhibit anorexigenic effect.
