A new efficient synthesis of L-fucose (and 6-alkyl analogs) in only six steps from D-mannose is described. This transfromation is based on addition of an organometallic reagent to the bis-acetonide of D-mannose followed by selective glycol cleavage with sodium periodate. Efficient separation of diastereomeric dibenzoates and formation of 2,5-di-benzyl (or benzoyl)-L-fucofuranose derivatives are also
描述了仅六步就从D-甘露糖合成L-岩藻糖(和6-烷基类似物)的新有效方法。这种转化是基于向D-甘露糖的双丙酮化物中添加有机金属试剂,然后用高碘酸钠选择性裂解乙二醇。还必须注意非对映异构体二苯甲酸酯的有效分离和2,5-二苄基(或苯甲酰基)-L-呋喃呋喃糖衍生物的形成。
