1,2-Diacetals in synthesis: Total synthesis of a glycosylphosphatidylinositol anchor of Trypanosoma brucei

A full account on a total synthesis of GPI anchor 1 employing butanediacetal (BDA) groups and a chiral bis(dihydropyran) is presented. The reactivity of selenium and thio glycosides was tuned by the use of BDA groups. This allowed the assembly of an appro
