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 a-galactosaminide/galactoside found in A- and B-Antigens, respectively, was achieved by using a unique di-tert-butylsilylene-directed a-glycosylation method. The proposed synthetic scheme provides an alternative to existing procedures for preparing ABO blood group antigens.© 2014 by the authors licensee MDPI Basel Switzerland.
