摘要

A series of glycosylated serine derivatives was synthesized from peracetylated sugars and Fmoc-protected serine; these were chemically esterified with the tris-(tetrabutylammonium) salt of pdCpA. The fully protected and deprotected glycosylated aminoacyl pdCpAs were ligated enzymatically to an abbreviated tRNA (tRNA-C(OH)) to provide the title compounds that are key intermediates in the elaboration of glycoproteins using readthrough of a nonsense codon.
