Naturally abundant pentacyclic triterpenoids are significant secondary metabolites which have aroused huge interest by possessing wide range of remarkable biological activities such as antitumor[1] antidiabetic[2] anti-inflammatory[3] and antiviral activities[4]. Oleanolic, ursolic acids and betulin are the most prominent compounds of this branch, which are isolated from various plants. The aim of this work is to obtain novel triterpenoid derivatives by C-H arylation at C(22). For this purpose, precursors bearing picolinic amide directing groups were synthesized.
