This application relates to efficient methods for the synthesis of ascarylose and its derivatives. A method for the production of ascarylose includes: providing, as a feedstock, a 1-O-substituted rhamnose; forming a mono-sulfonate ester at the 3-OH group of the 1-O-substituted rhamnose; and treating the mono-sulfonate ester with a hydride source to form a 1-O-substituted ascarylose. Forming the mono-sulfonate ester can advantageously be conducted on a 1-O-substituted rhamnose without hydroxyl protecting groups at either the 2-OH or 4-OH-positions.
本申请涉及制备ascarylose及其衍生物的高效方法。一种制备ascarylose的方法包括:提供1-O-取代的鼠李糖作为原料;在1-O-取代的鼠李糖的3-OH基团上形成单磺酸酯;并使用氢化物来源处理单磺酸酯以形成1-O-取代的ascarylose。优选地,在2-OH或4-OH位置均不具有羟基保护基团的1-O-取代鼠李糖上可以有利地形成单磺酸酯。
