known methods to synthesize aryl trifluoromethyl ethers require harsh reagents and highly controlled reaction conditions and rarely occur when heteroaromatic units are present. The two-step O-trifluoromethylation of phenols via aryl xanthates is one such method that suffers from these drawbacks. Herein, we report a method for the synthesis of aryl trifluoromethyl ethersfrom phenols by the facile conversion
The present invention relates to compounds, which are useful for treatment and/or prevention of diabetes mellitus, diabetes mellitus complications or obesity, since the compounds have glucokinase-activating effects, and are presented in Formula (I): wherein R1 represents a carbamoyl group; R2 represents a lower alkyl group; both of X1 and X2 represent CH, or any one of X1 and X2 represents a nitrogen atom and the other represents CH; a group of represents a group selected from the group consisting of a pyridinyl, a pyrazinyl, a pyrazolyl, a thiadiazolyl, a triazolyl, an isoxazolyl and a thiazolyl group; and k is zero or 1, or relates to pharmaceutically acceptable salts thereof.
