Abstract
A new series of 2-oxoallobetulin derivatives has been synthesized by using various unique reactions. Site-specific or regio-selective functionalization of those compounds has been investigated. In all cases, the reactions only happened at C-3 position except the synthesis of lactam happened at C-1 position. The intermediates leading to the novel allobetulin derivatives have also been described.
