L-Glucose derivatives are prepared by two different routes. The first involves a modification of the previously reported multi-step approach by Shiozaki8, starting from a D-glucurono-1,5-lactone derivative, resulting in the isolation of 2,3,4,6-tetra-O-benzyl-L-glucopyranose. The other route comprises the synthesis of penta-O-acetyl-L-glucopyranose via a highly stereoselective addition of [(phenyl
L-葡萄糖衍生物是通过两种不同的途径制备的。首先涉及Shiozaki 8对先前报道的多步骤方法的修改,从D-葡萄糖醛酸-1,5-内酯衍生物开始,分离出2,3,4,6- tetra - O-苄基- L-吡喃葡萄糖。另一途径包括通过高立体选择性地加入[(苯基二甲基甲硅烷基)甲基]氯化镁与2,3,5-三-O-苄基-L-呋喃糖合成五-O-乙酰基-L-吡喃葡萄糖。
