Carbohydrate Sulfonyl Chlorides for Simple, Convenient Access to Glycoconjugates
摘要:
[GRAPHICS]The use of carbohydrate sulfonyl chlorides is introduced as a new, facile glycoconjugation method which could find broad applications. We demonstrate the approach by synthesizing a number of glycosylated cholesterol absorption inhibitors which display high inhibitory efficacies in our recently established in vitro assay. Furthermore, we highlight an advantage of the electron-withdrawing nature of the suffonyl linkage which allowed the synthesis of otherwise unstable azetidine conjugates.
