该中间体在本合成路线中的序号:(XVIII)The methanolysis of vitamin D2 tosylate (XIV) gives the cyclovitamin (XV), which is oxidized with SeO2 and tert-butyl hydroperoxide in dichloromethane yielding the 1alpha-hydroxy cyclovitamin (XVI). The acylation of (XVI) with acetic anhydride affords the acetate (XVII), which is rearranged with TsOH in hot dioxane to provide 1alpha-acetodyvitamin D2 (XVIII). Finally, this com-pound is hydrolyzed with KOH in aqueous methanol.
