摘要

organic chemistry, chemical technology. SUBSTANCE: invention describes stereoselective method of synthesis of substituted dihydro-2,3-benzodiazepines of the formula (I) where R is H, C1-10-alkyl; X is H, C1-10-alkyl, acyl, aryl, carboxyl or its substituted derivative of protective group, or pharmaceutically acceptable salt, by cyclization of compound of the formula (II) . Compounds of the formula (I) are useful as antagonists of AMPA-receptors. EFFECT: improved method of synthesis, valuable pharmacological properties. 20 cl, 1 tbl, 29 ex
