METHOD FOR PREPARING 3beta-ACETOXY-20,20-DIMETHOXYNORTARAXASTANE

摘要

FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to novel method for synthesis of 3beta-acetoxy-20,20-dimethoxynortaraxastane of the formula (1): . Method is carried out by interaction of 3beta-acetoxy-20-methylenetaraxastane in chloroform solution with ozone excess in the mole ratio 3beta-acetoxy-20-methylenetaraxastane : ozone = 1:1.5 with addition of methanol, at room temperature and stirring. The yield of the end product is 68%. ^ EFFECT: improved method of synthesis. ^ 2 cl, 1 ex
