have been developed; however, extension of this reactivity to remote C-H functionalizations through large-ring rhodacyclic intermediates has yet to be demonstrated. Herein we report the first example of the use of a U-shaped nitrile template to direct Rh(III)-catalyzed remote meta-C-H activation via a postulated 12-membered macrocyclic intermediate. Because the ligands used for Rh(III) catalysts are
to synthesize cinacalcet hydrochloride ((R)‐α‐methyl‐N‐[3‐[3‐(trifluoromethyl) phenyl] propyl]‐1‐naphthalene methane amine hydrochloride) has been described. The key steps include the Knoevenagel–Doebnercondensation and the amide reduction under milder conditions.
