2-Nitro-derivatives of allobetulone were prepared by reaction of allobetulin with nitric acid. 2 beta-Aminoallobetulin was synthesized by reduction of 2-nitrobetulone with LiAlH4. The corresponding allobetulin seco-derivatives were obtained via oxidation by H2O2 in the presence of K2CO3 of 2-nitroallobetulone and cleavage of 2,2-dinitroallobetulone by K2CO3 in H2O:THF.
