建立了一种合成人ABO组织血型2型抗原决定簇的新方法。以乳果糖为原料,经Heyns重排反应得到N-邻苯二甲酰基保护的乳糖胺硫代糖苷,得到了一种2型核心二糖。该方案的使用减少了反应步骤的总数。分别在A和B抗原中发现的α-半乳糖胺/半乳糖苷的立体选择性构建是通过一种独特的二叔丁基硅烯直接α-糖基化方法实现的。拟议的合成方案为现有的ABO血型抗原制备程序提供了一种替代方案。
A new chemical approach to synthesizing human ABO histo-blood type 2 antigenic determinants was developed. N-Phthaloyl-protected lactosaminyl thioglycoside derived from lactulose via the Heyns rearrangement was employed to obtain a type 2 core disaccharide. Use of this scheme lowered the overall number of reaction steps. Stereoselective construction of the α-galactosaminide/galactoside found in A- and B-antigens, respectively, was achieved by using a unique di-tert-butylsilylene-directed α-glycosylation method. The proposed synthetic scheme provides an alternative to existing procedures for preparing ABO blood group antigens.
