Oxazolidine-2-one derivatives.

摘要

The invention relates to oxazolidin-2-one derivatives of the formula wherein R is hydrogen or lower alkyl; X is cycloalkenyl; bicyclo[2.2.1]hept-2-yl, opt. substituted by phenyl-2-oxo-5-methoxymethyloxazolidinyl; bicyclo[2.2.1]hept-5-en-2-yl; adamantyl; or cycloalkyl or piperidine, optionally mono- or polysubstituted by halogen, amino, lower alkyl, nitrile, an oxo group, hydroxyimino, ethylenedioxy or by -OR<1>, wherein R<1> is -CH(C6H5)2, -(CH2)nC6H5, lower alkyl, hydrogen, - (CH2)nNHCOCH3, -(CH2)nNH2, -(CH2)nSOCH3, -(CH2)nCN, -(CH2) nSCH3, -(CH2)nSO2CH3, -CO-lower alkyl, -COC6H5, opt. substituted by an oxazolidinyl group: or by =CR<2>R<3>, wherein R<2> is hydrogen or lower alkyl; R<3> is hydrogen, nitrile, lower alkyl, phenyl or COO-lower alkyl; or by -(CH2)nR<4>, wherein R<4> is nitrile, amino, -NHCOCH3, -COC6H5Hal, phenyl or hydroxyl; or by -COR<5>, wherein R<5> is lower alkyl, -CH=CH-C6H5, -C6H5CF3, -O-C(CH3)3 or -O-lower alkyl; or by -NR<6>R<7>, wherein R<6> is hydrogen or -COCH3; R<7> is -COCH3, benzyl or -(CH2)nNHCOC6H4Hal; n is 1-3; Y<1> is -CH= or -N=; Y<2> is -CH=, -C(OH)=, -C(NO2)=, -C(NH2)=, -C(Hal)= or -N= and pharmaceutically acceptable salts of basic compounds of the formula I with acids. These novel compounds and their pharmaceutically acceptable salts can be used for the prevention or control of depressive states, panic and anxiety states, cognitive disorders and neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease.
