Abstract
The invention comprises optically active 2-(alkoxycarbonylmethyl) - 3 - alkyl - 9,10 - di - methoxy - 1,4,6,7 - tetrahydro - 11bH - benzo [a]quinolizines where the alkyl and alkoxy radicals contain not more than 4 carbon atoms, and compounds of the formulae <FORM:1024902/C2/1> (wherein R and R1 represent C1-4 alkyl radicals) and acid addition salts of the compounds of the Formula III having the tautomeric formula <FORM:1024902/C2/2> (wherein X1 represents an anion). (+)-2-(Alkoxycarbonylmethyl - 3 - alkyl - 9,10 - dimethoxy - 1,4,6,7 - tetrahydro - 11bH - benzo [a]quinolizine may be obtained by separating a racemic-mixture of the (+) and (-) forms by, for example, fractional crystallization of the optically active salts with an optically active acid. (-)-2-(Alkoxycarbonylmethyl) - 3 - alkyl-9, 10 - dimethoxy - 1,4,6,7 - tetrahydro - 11bH-benzo[a]quinolizine is made by oxidizing the corresponding (+) isomer with a mercuric, cupric or ferric salt to give a compound of the Formula III and reducing said oxidation product and separating the resulting racemic 2-(lower alkoxycarbonylmethyl) - 3 - (lower alkyl) - 9,10 - dimethoxy - 1,4,6,7 - tetrahydro-11bH - benzo[a]quinolizine into its (+) and (-) forms and, if desired, recycling the (+)-form.
