[Synthesis and modification of triterpenoids with two lupan backbones].
The first derivatives containing two lupan backbones were synthesized by the interaction of betulonic acid chloride with diols (ethylene glycol and diethylene glycol) and monoethanolamine. A modification of ring A of ethylene-l,2-bis(betulonnate) led to its bis(3beta-aminopropyloxy) and bis(3,4-seco-2-cyano) derivatives.
