    • Significant advances in this type of problem arose through the use of Ellman's Fmoc-based sulfonamide linker (Shin, Y.; Winans, K. A.; Backes, B. J.; Kent, S. B. H.; Ellman, J. A.; Bertozzi, C. R. J. Am. Chem. Soc. 1999, 121, 11684-11689), which has been employed in the synthesis of glycopeptide thioesters. The method we practice here, however, insists on maximal convergence, as opposed to a "cassette" approach to glycan incorporation. We note that certain glycosidic linkages (e.g., fucosidic linkages in erythropoietin) are particularly unstable toward the acidic conditions (TFA) required for protecting group cleavage. Other "cassette"-based Fmoc solid-phase peptide synthesis (SPPS) techniques potentially leading to glycopeptide thioesters also include acidic conditions at some point. These methods involve alteration of the Fmoc deblocking conditions [(a) Li, X. Q.; Kawakami, T.; Aimoto, S. Tetrahedron Lett. 1998, 39, 8669-8672. (b) Clippingdale, A. B.; Barrow, C. J.; Wade, J. D.

Tetrahedron Lett. 2003, 44, 2961-2964], or direct conversion into thioesters of C-terminal acids (von Eggelkraut-Gottanka, R.; Klose, A.; Beck-Sickinger, A. G.; Beyermann, M. Tetrahedron Lett. 2003, 44, 3551-3554), esters (Swinnen, D.; Hilvert, D. Org. Lett. 2000, 2, 2439-2442), or trithioortho esters (Brask, J.; Albericio, F.; Jensen, K. J. Org. Lett. 2003, 5, 2951-2953). Boc-based SPPS employs strongly acidic cleavage conditions (liquid HF) that are incompatible with many glycosidic linkages.
