Block glycosylation of a T antigen–threonine conjugate with a sialyl Lewis x trichloroacetimidate was used to synthesize a sialyl Lewis x –T antigen–threonine building block. Selective protecting‐group manipulations furnished a compound with exclusively acetyl‐protected functions in the carbohydrate portion; this intermediate is sufficiently acid‐stable that it is applicable to the solid‐phase synthesis of binding site A of the P‐selectin ligand PSGL‐1.
