Application of the glycal assembly method to the concise synthesis of neoglycoconjugates of Le(y) and Le(b) blood group determinants and of the H-type I and H-type II oligosaccharides

The power of the glycal assembly strategy for reaching Lewis and H-type blood group determinants is demonstrated herein. Three key elements form the basis of the method. Thus, α-epoxides derived from galactal cyclic carbonate 13 are produced stereospecifi
