Synthesis of fused polycyclic indoles via Cu(II)-catalyzed intramolecular cyclization of N-(2-cyanophenyl)indoles in the presence of diaryliodonium salts
A novel and mild method for the synthesis of fused polycyclic indoles of [1,2-a]indol-10-imines via a Cu(OTf)2-catalyzed the intramolecular cyclization of N-(2-cyanophenyl)indoles in the presence of diaryliodonium salts has been developed.
通过Cu(OTf)2合成[1,2 - a ]吲哚-10-亚胺的稠合多环吲哚的新颖温和的方法在存在下,催化N-(2-氰基苯基)吲哚的分子内环化。已开发出二芳基碘鎓盐。

[Problems] To provide a compound that is useful as an agent for treating chronic renal insufficiency or an agent for treating diabetic nephropathy.
[Means for Solving Problems] The present inventors have conducted extensive studies on a compound having an EP4 receptor antagonistic action, and as a result, they have found that various amide derivatives having a carboxylic group or an equivalent thereof exhibit an excellent EP4 receptor antagonistic action, thereby completing the present invention.
Since the compound of the present invention has an excellent EP4 receptor antagonistic action, it is useful as an agent for preventing and/or treating chronic renal insufficiency or diabetic nephropathy.
