Biologically active, enantiomerically substantially pure intermediates of trans-hexahydro-benzo[d]naphtho[2,1-b] azepines are prepared.
The present invention involves a process for preparing compounds of the general formula 3:
Each R¹ is independently H or alkyl;
Q is methylene, -O- or -S-;
m and n are independently variable and may each have a value of 0, 1 or 2 with the provisos that the sum of m and n is not greater than 3, that m may not equal zero when Q is -O- or -S-, and that when Q is -CH₂-, m and n cannot both be zero;
X is hydrogen, halo, alkyl, alkylthio, alkylsulfinyl, alkylsufonyl, hydroxy, alkoxy or trifluoromethyl;
Y is hydrogen, hydroxy, alkoxy, -OC(O)NR²R³, -OC(O)-R⁹, -N(R¹)₂, -NHC(O)R¹ or -OP(O)(OH)OR¹;
R² and R³ are the same or different and each is hydrogen (provided that both are not hydrogen), alkyl, aralkyl, cycloalkyl, aryl, hydroxyalkyl, or alkoxyalkyl;
in addition, when one of R² and R³ is as defined above, the other may be -R⁴NR⁵R⁶ wherein R⁴ is alkanediyl, R⁵ is hydrogen or alkyl and R⁶ is alkyl, or R⁵ and R⁶ together with the nitrogen atom form a 1-azetidinyl, 1-pyrrolidinyl, 1-piperidinyl, 1-(4-alkylpiperazinyl), 4-morpholinyl or 1-(hexahydroazepinyl) group};
in further addition, R² and R³ together with the nitrogen atom may form a 1-azetidinyl, 1-pyrrolidinyl, 1-piperidinyl, 4-morpholinyl, 1-(4-alkylpiperazinyl), 1-(4-alkoxyalkylpiperazinyl), 1-(4-hydroxyalkylpiperazinyl), 1-(3-hydroxyazetidinyl), 1-(3-alkoxyazetidinyl), 1-(-hydroxypyrrolidinyl), 1-(3-alkoxypyrrolidinyl), 1-(3- or 4-hydroxypiperidinyl), 1-(3- or 4-alkoxypiperidinyl), 1-(4-oxopiperidinyl) or 1-(3-oxopyrrolidinyl) ring;
in still further addition, when R² is hydrogen, R³ may be -CHR⁷CO₂R⁸, wherein R⁷ and R⁸ are the same or different and each is hydrogen, alkyl or aralkyl;
R⁹ is alkyl, aralkyl, aryl, alkoxyalkyl, aryloxyalkyl, aralkoxyalkyl, cycloalkylalkyl, alkoxycarbonylalkyl, cycloalkyl, 1-adamantyl, cycloalkoxyalkyl, alkoxy, aralkyloxy, cycloalkoxy, aryloxy or -CHR⁷NHR⁸ ; and
Z is X as defined above, amino, alkylamino or -NHC(O)R¹⁰ wherein R¹⁰ is hydrogen, alkyl or aryl};
R¹¹ is H or alkyl;
R¹² is alkyl;
with the proviso that R¹¹ and R¹² are different, and K is hydrogen, alkoxy, hydroxyl, arloxy or alkyl.
