The invention relates to quinoline derivatives as well as their pharmaceutically acceptable salts. The invention further relates to a process for the preparation of such compounds. The compounds of the invention are glycine B antagonists and are therefore useful for the control and prevention of various disorders, including neurological disorders.
A Direct C2-Selective Phenoxylation and Alkoxylation of Quinoline <i>N</i>
-Oxides with Various Phenols and Alcohols in the Presence of <i>H</i>
-Phosphonate
A practical and efficient method for the synthesis of 2-aroxy(alkoxy)quinolines has been developed, via direct cross-dehydrogenativecoupling reaction between quinoline N-oxides and readily available phenols and alcohols in the presence of H-phosphonate and CCl4 under mild conditions.
The invention relates to quinoline derivatives as well as their pharmaceutically acceptable salts. The invention further relates to a process for the preparation of such compounds.

activating agent-promoted deoxygenative aryloxylation/amination. The main challenges in constructing C2–O or C2–N bonds from N-oxides lie in overcoming two side reactions: the reaction between the activating agent and the nucleophile, and the associated reaction at the C4-position. Compared to previous reports, this method benefits from an eco-friendly solvent, short reaction time, simple operation, and wide
