ABSTRACT:
Compounds of Formula I have been shown to enhance the release of the neurotransmitters acetylcholine, dopamine and serotonin; and thus may be useful in the treatment of diseases of man where subnormal levels of this neurochemical are found such as in Alzheimer's disease and other conditions involving learning and cognition; and Parkinson's disease.
The compounds of this invention can be described as shown in Formula I ##STR1## where A is a heteroaromatic system.
