of arenes bearing ortho/para directing group(s) using the iridium‐catalyzed C−H borylation reaction followed by a newly developed copper(II)‐catalyzed transformation of the crude aryl pinacol boronate esters into the corresponding nitroarenes in a one‐pot fashion. This protocol allows the synthesis of meta‐nitrated arenes that are tedious to prepare or require multistep synthesis using the existing

describe the discovery of a novel class of oxadiazole derivatives from which potent and selective CB2 agonist leads were developed. Initial hit 7 was identified from a cannabinoid target-biased library generated by virtual screening of sample collections using a pharmacophore model in combination with a series of physicochemical filters. 7 was demonstrated to be a selective CB2 agonist (CB2 EC50 = 93
