Silylated furanoid glycals are synthesized in high yields by elimination of the nucleobase in thymidine (1a) and 5′-O- (tert-butyldiphenylsilyl)thymidine (1b) on treatment with 1,1,1,3,3,3-hexamethyldisilazane (HMDS) in the presence of ammonium sulfate at reflux temperature for 2 hours.
在硫酸铵存在下,用 1,1,1,3,3,3-hexamethyldisilazane (HMDS)在回流温度下处理 2 小时,消除胸苷(1a)和 5′-O-(叔丁基二苯基硅基)胸苷(1b)中的核碱基,即可高产合成硅呋喃糖醛。
