The present invention relates to tetrahydroquinolines and related compounds. More particularly, the present invention relates to 5-amino-5,6,7,8-tetrahydroquinolines of the formula
wherein X-Y is a group of the formula
wherein R is hydrogen, alkyl, alkenyl, alkynyl, or arylalkyl, or a group of the formula
wherein R¹ is hydrogen, alkyl or arylalkyl; R² and R³ are independently hydrogen, alkyl, arylalkyl, diarylalkyl, cycloalkenylalkyl, alkoxy, arylalkoxy, or alkanoyl; R² and R³ taken together with the nitrogen atom to which they are attached form a group of the formula
wherein p is 0 or 1, a group of the formula
wherein Z is O, S, or a group of the formula NR⁶ wherein R⁶ is hydrogen, alkyl, or arylalkyl; R⁴ is hydrogen, alkyl or arylalkyl; R⁵ is hydrogen, alkyl or arylalkyl; and m is 0, 1, or 2, and n is 1 or 2; or geometrical and optical isomers thereof, or a pharmaceutically acceptable salt thereof, which are useful for relieving memory dysfunction,
The invention relates further to a process for the preparation of these compounds and their use as medicaments.
