The synthesis and SAR of 2-arylsulfanylphenyl-1-oxyalkylamino acids as GlyT-1 inhibitors
摘要:
Elevation of glycine levels by inhibition of the glycine transporter-1 (GlyT-1) and activation of the NMDA receptor is a potential strategy for the treatment of schizophrenia. A novel series of 2-arylsulfanylphenyl-1-oxyalkyl amino acids have been identified. The most prominent member of this series S-1-{2-[3-(3-fluoro-phenylsulfanyl)biphenyl-4-yloxy]ethyl} pyrrolidine-2-carboxylic acid (38) is a potent GlyT-1 inhibitor (IC50 = 59 nM). In vitro and in vivo assessment of CNS exposure indicates this compound is a likely substrate for active efflux transporters. (c) 2006 Elsevier Ltd. All rights reserved.

A novel method for the formation of 2-arylsulfanylphenols fromthiols and cyclohexanones is described. Iodine was used as an effective catalyst for this kind of transformation. Cyclohexanones were used as a phenol source via a dehydrogenation and tautomerization reaction.

by the direct oxidation of aryl Grignard reagents using compressed air in continuous gas‐liquid segmented flow systems is described. The process tolerates a broad range of functional groups, including oxidation‐sensitive functionalities such as alkenes, amines, and thioethers. By integrating a benzyne‐mediated in‐line generation of arylmagnesium intermediates with the aerobic oxidation, a facile three‐step

A novel method for the formation of 2-arylsulfanylphenols using cyclohexanones as phenol source via dehydrogenation is described. Various aromatic sodium sulfinates and sulfonyl chlorides acted as efficient coupling partners to construct new C–S bonds in the presence of an iodine promoter.
