Intermediate compounds for the synthesis of glycolipids

摘要

The invention provides important intermediate compounds for the synthesis of acidic glycolipids which are identical with the glycolipid antigens isolated from the acidic glycolipid fractions of peripheral nerve and embryonic central nervous system and preparation methods thereof. By the adoption of the present intermediate compounds, sulfation of 3-hydroxyl group of end glucuronic acid portion of the acidic glycolipid can be quite easily carried out and total synthetic yield be greatly improved.
