Synthesis of Betulin and Allobetulin Derivatives Containing Heterylthioacetoxyl Groups
摘要
Abstract
Previously unknown betulin and allobetulin derivatives, which are of interest as potential biologically active substances, were synthesized by replacing chlorine in 3,28-bis(chloroacetoxy)betulin and 3-chloroacetoxyallobetulin with pharmacophoric cycloheteryl sulfide groups.
