to the publication of many different syntheses. However, almost all of them focused on the methodology development rather than a scalable synthesis. Herein, we have described a practical and scalable procedure for the synthesis of KRN7000 basing on the glycosyl iodide method. This procedure involves total of eight steps to obtain the highly pure product KNR7000 on gram scale from the commercially available
KRN7000特别有用,因为它是一种功能强大且特异的CD1d激动剂,在过去25年中引起了人们对免疫学的浓厚兴趣。它的有限的商业可用性和高昂的价格导致许多不同合成方法的发表。但是,几乎所有的研究者都专注于方法学的发展而不是可扩展的综合。在此,我们已经描述了一种基于糖基碘化物方法合成KRN7000的实用且可扩展的程序。该过程涉及总共八个步骤,仅需三步色谱纯化,即可从市售起始原料(d-半乳糖和植物鞘氨醇)中获得克级的高纯度产品KNR7000 。
