CYCLIC AMINOCOMPOUND OR ITS PHYSIOLOGICALLY ACCEPTABLE ADDITIVE ACID SALT Russian patent published in 1994 - IPC

FIELD: organic chemistry. SUBSTANCE: product - cyclic aminocompound of the formula 1 where R - pyridyl, piperidyl or pyrrolidinyl each of which can be substituted with lower alkyl, lower alkylcarbonyl, carbobenzoxy, naphthylcarbonyl (lower) alkyl, phenylhydroxy (lower) alkyl, phenylcarbonyl (lower) alkyl or phenyl (lower) alkyl each of which can be substituted with halogen atom or lower alkoxy; p = 1 or 2; A - bond or two - or trivalent aliphatic C_1-6 - hydrocarbon residue which can be substituted which lower alkyl, OXO, hydroxyimino or hydroxy-group. - a simple or double bond at the following condition: when A - is a bond then means simple bond; R₂ - and R₃ - are independently hydrogen atom or lower alkyl which can be substituted with phenyl or piperidyl at condition that both R₂ and R₃ are not hydrogen atom; or R₂ and R₃ together with adjacent nitrogen atom form piperidine, hexamethyleneimine-group, morpholine, pyrrolidine, piperazine or 1-imidazole group each of which can be substituted with lower alkyl, lower alkylcarbonyl or diphenyl (lower) alkyl or its physiologically acceptable additive acid salt.
