Esterification of Betulin 3-Acetate in Melts of Some Organic Acids

Synthetic methods for betulin 3-acetate-28-benzoate, betulin 3-acetate-28-p-bromobenzoate, betulin 3-acetate-28-cinnamate, betulin 3-acetate-28-succinate, and betulin 3-caetate-28-phthalate based on the reaction of betulin 3-acetate with fused benzoic, p-bromobenzoic, cinnamic, succinic, and phthalic acids at 185 –195°C for 5–6 min are proposed for the first time.
