摘要：

Synthesis of the natural product 2beta-hydroxyursolic acid (6) has been achieved through reaction of ursonic acid (1) with SeO2, and subsequent stereospecific reduction of the 2,3-diketo derivative (3) and its tautomer diosphenol (4), with NaBH4 under mild reaction conditions. Several other analogues (2), (5), (7) and (8) of the ursane series have also been obtained during these reactions.
