Syntheses of Functionalized 1,4-Disubstituted γ-Carbolines
摘要:
We report the complete synthesis of a variety of 1,4-disubstituted gamma-carbolines. These compounds are of particular interest for their involvement in many biological processes and are believed to possess various medicinal activities. A large number of N-tosylaldimines were condensed with indoles affording an array of 3-aminomethyl indoles. Subsequent additions, followed by intramolecular cyclization, afforded an array of 1,2-dihydro-3H-gamma-carbolones in good yield. Upon subsequent aromatization, the corresponding fully aromatic functionalized 1-aryl-4-hydroxy-gamma-carbolines resulted.
The present invention concerns the compounds of the formula:
and the prodrug and salts thereof, wherein R may be a hydroxyl or other pendent group and Ar is an aryl. The compositions may be adapted for the treatment of neurodegenerative diseases. Further, the compositions may be adapted as a pharmaceutical such as an antipsychotic pharmaceutical, an antibiotic pharmaceutical, an antiviral pharmaceutical or an antitumor pharmaceutical.

We report the novel synthesis of various highly functionalized 3-arylaminomethyl indoles. This synthetic approach makes use of the directing ability of a bulky tert-butyldimethylsilyl-protecting group, which directs the condensation of an array of aromatic tosylaldimines specifically into the 3-position of the indole nucleus. The reactions, which occur under relatively mild conditions, afford the desired
