Catalytic Acylation of Amines with Aldehydes or Aldoximes
摘要:
The simple nickel salt NiCl2 center dot 6H(2)O catalyzes the coupling of aldoximes with amines to give secondary or tertiary amide products. The aldoxime can be prepared in situ from the corresponding aldehyde. The use of O-18-labeled oximes has allowed insight into the mechanism of this reaction.

This invention concerns novel substituted tetracyclic tetrahydrofuran derivatives containing a cyclic amine side chain with binding affinities towards dopamine receptors, in particular dopamine D
2
receptors, towards serotonin receptors, in particular 5-HT
2A
and 5-HT
2C
receptors, and pharmaceutical compositions comprising the compounds according to the invention, the use thereof as a medicine, in particular for the prevention and/or treatment of a range of psychiatric and neurological disorders, in particular certain psychotic, cardiovascular and gastrokinetic disorders and processes for their production.
The compounds according to the invention can be represented by general Formula (I)
and comprises also a pharmaceutically acceptable acid or base addition salt thereof, an N-oxide form thereof or a quaternary ammonium salt thereof, wherein all substituents are defined as in Claim 1.
Alpha-helix mimetic structures and compounds represented by the formula (I) wherein the general formula and the definition of each symbol are as defined in the specification, a chemical library relating thereto, and methods relating thereto, are disclosed. Applications of these compounds in the treatment of medical conditions, e.g., cancer diseases, fibrotic diseases, and pharmaceutical compositions comprising the mimetics are further disclosed.
