Abstract
The invention comprises compounds of the general formula <FORM:0893920/IV (b)/1> (wherein R1 represents hydrogen, an alkyl or alkoxyalkyl radical of not more than 6 carbon atoms, or a benzyl radical, R2 represents hydrogen or a C1-6 alkyl radical, R3 and R4 represent hydrogen atoms or jointly a methylenedioxy radical, A represents -CH2CH2- or -CH=CH-, and Z represents oxygen or CH2) and their acid addition salts, and the preparation thereof by the following processes: (a) (where R1 is other than hydrogen, R2 is hydrogen and A is -CH2CH2-) reacting an imine of the general formula <FORM:0893920/IV (b)/2> (wherein X represents a halogen atom and R5 represents an alkyl or alkoxyalkyl radical of not more than 6 carbon atoms or a benzyl radical) with a reactive organometallic compound under anhydrous conditions and decomposing the product with an aqueous medium; (b) (when R1 is hydrogen and R2 is CH3) reducing a carbamate of the general formula <FORM:0893920/IV (b)/3> (c) (when R1=R2=H) hydrolysing a carbamate of the general formula given in (b); (d) (when R1=R2=H and A is -CH2CH2) catalytically hydrogenating the N-monobenzyl derivatives of the desired products; (e) (when R2 is C1-6 alkyl) alkylating the compounds in which R2 is hydrogen (e.g. by acylation followed by reduction); (f) (when R1 is hydrogen or C1-6 alkyl and A is -CH2CH2-) catalytically hydrogenating the corresponding compounds in which A is -CH=CH-. The products are p useful as central nervous system depressants (see Group VI). Imines of the second general formula above are prepared by condensing a primary amine with the corresponding ketones, obtainable, when Z is oxygen, from a sodium o-halophenate and a 2-halocylohexanone, or, when Z is CH2 from an o-halobenzyl halide and cyclohexanone in the presence of sodamide. Carbamates of the third general formula above (R3=R4=H) are prepared by esterifying indene- or benzofuran-3-carboxylic acid to an alkyl ester, reacting this with butadiene to form an alkyl ester of 1,4,4a,9a-tetrahydrofluorene-4a-carboxylic acid or 5a,6,9,9a-tetrahydrodibenzofuran-9a-carboxylic acid and then performing the transformations <FORM:0893920/IV (b)/4> preceded, if desired, by <FORM:0893920/IV (b)/5>ALSO:Compounds of the general formula <FORM:0893920/VI/1> (wherein R1 represents hydrogen, an alkyl or alkoxyalkyl radical of not more than 6 carbon atoms, or a benzyl radical, R2 represents hydrogen or a C1-6 alkyl radical, R3 and R4 represent hydrogen atoms or jointly a methylenedioxy radical, A represents -CH2CH2- or -CH = CH-, and Z represents oxygen or CH2) and their addition salts with inorganic or organic acids (including ascorbic acid) may be administered orally or parenterally as central nervous system depressants. For anaesthetic purposes they may be used in combination into barbiturates.
