Using cyclopalladated ferrocenylimine complexes (1-3 mol%) as catalysts, the Suzuki-Miyaura coupling of potassium N,N-dialkylaminomethyltrifluoroborates with aryl and heteroaryl halides were carried out in a 10:1 THF-H2O mixture at 80 ËC in the presence of Cs2CO3 (3.0 equiv) as base, giving the desired cross-coupling products in 14-87% yields. A variety of potassium alkyltrifluoroborates were also examined.

The present invention relates to novel carboxamide compounds and their use for the manufacture of a medicament. The carboxamide compounds are inhibitors of calpain (calcium dependant cysteine proteases). The invention therefore also relates to the use of these carboxamide compounds for treating a disorder associated with an elevated calpain activity.
The carboxamide compounds are compounds of the general formula I

The antiplasmodial activity, DMPK properties, and efficacy of a series of quinoline-4-carboxamides are described. This series was identified from a phenotypic screen against the blood stage of Plasmodium falciparum (3D7) and displayed moderate potency but with suboptimal physicochemical properties and poor microsomal stability. The screening hit (1, EC50 = 120 nM) was optimized to lead molecules with
Disclosed is a five-membered ring compound represented by formula (1) or a pharmaceutically acceptable salt thereof. The compound inhibits infiltration of leukocytes including eosinophils and lymphocytes, and is effective as a drug for treating various inflammations. The compound is highly safe and can be administered for a long period. A pharmaceutical product containing the five-membered ring compound or a pharmaceutically acceptable salt thereof is also disclosed.
