Abstract The facile and efficient multigram synthesis of (±)-tropan-2-one 1 was achieved in six steps (65% overall yield) from N-methyl-3-oxopyridyl hydroiodide 3.
The present invention relates to a compound of formula I
wherein
R
1
, R
2
and R
3
are each independently hydrogen, lower alkyl, lower alkoxy, cycloalkyl, lower alkyl substituted by halogen or S-lower alkyl;
or to a pharmaceutically acceptable acid addition salt, racemic mixture, or corresponding enantiomer and/or optical isomer thereof. The compounds of formula I are good inhibitors of the glycine transporter 1 (GlyT-1), and have a good selectivity to glycine transporter 2 (GlyT-2) inhibitors. The compounds can be used in the treatment of neurological and neuropsychiatric disorders.
The present invention relates to a compound of general formula (I) wherein R1, R2 and R3 are independently from each other hydrogen, lower alkyl, lower alkoxy, cycloalkyl, lower alkyl substituted by halogen or S-lower alkyl; or to a pharmaceutically acceptable acid addition salt, to a racemic mixture, or to its corresponding enantiomer and/or optical isomer thereof. It has been found that the compounds of general formula (I) are good inhibitors of the glycine transporter 1 (GlyT-1), and that they have a good selectivity to glycine transporter 2 (GlyT-2) inhibitors. The compounds may be used in the treatment of neurological and neuropsychiatric disorders.
This invention is directed to 3-(diarylmethylene)-8-azabicyclo[3.2.1]octane derivatives useful as &dgr;-opioid or &mgr;-opioid receptor modulators. Depending on their agonist or antagonist effect, the compounds are useful analgesics, immunosuppressants, antiinflammatory agents, agents for the treatment of neurological and psychiatric conditions, medicaments for drug and alcohol abuse, agents for treating gastritis and diarrhea, cardiovascular agents and agents for the treatment of respiratory diseases.
