The Sonogashira reaction can be applied for the preparation of acetylenic derivatives of betulonic acid where the triterpenoid moiety can serve as either the halo- or the acetylenic component. This reaction opened access to the first derivatives of betulonic acid containing either the arylethynyl (СС-Ar(Het) or the ethynyl (ССН) moieties. From the fundamental perspective, this work illustrates the
