A simple and effective method for formylation of betulin using formic acid and 3a,6a-diphenylthioglycoluril is reported. The yield of betulin diformate was 87%. Allobetulin formate (95%) was prepared by reacting betulin diformate with trifluoroacetic acid. The structures of betulin diformate and allobetulin formate were confirmed by IR and NMR spectroscopy. The antioxidant activity of the synthesized compounds was studied.
