readily available phenols and glucose was accomplished. A simple method for the synthesis of phenolglycosides derivatives of 2-acyloxy salicyl and gentisyl alcohol was developed. The key step of these natural products' synthesis is a selective removal of acetyl groups in the presence of other acyl groups.
水杨科的某些天然酚类糖苷的总合成,即:salireposide,populosides A,B和C,而在植物中不存在脱氧水杨苷(2-(β-D-吡喃葡萄糖基氧基)-苄基苯甲酸酯)和异水杨苷的过乙酸(2-(β-D-吡喃葡萄糖基氧基)-5-苯甲酰氧基苄醇),是从容易获得的酚和葡萄糖开始的。开发了一种简单的合成2-酰氧基水杨基和龙胆醇的酚苷衍生物的方法。这些天然产物合成的关键步骤是在其他酰基存在下选择性除去乙酰基。
