This invention relates to compounds of formula (I), a process for their preparation, pharmaceutical compositions containing them and their use in the treatment of conditions having an association with the orexin sub-type 1 receptor. Ar1 and Ar2 have meanings given in the description.
Site-selective synthesis of functionalized dibenzo[<i>f</i>,<i>h</i>]quinolines and their derivatives involving cyclic diaryliodonium salts <i>via</i> a decarboxylative annulation strategy
report a site-selective synthesis of functionalized dibenzo[f,h]quinolines and their derivatives, which could be used as OLED materials. The key step is the double cross coupling reaction between the 2-chloropyridinyl acids and the cyclic diaryliodonium salts, where the carboxylic acid was unprecedentedly employed as both a traceless directing group and a functional handle in a one-pot atom- and step-economical
