3-Dimethylphosphinothioyl-2(3H)-oxazolone (MPTO) was synthesized, and its ability to effect racemization-free couplings and cyclization of a peptide and its C-terminal epimer was examined. MPTO showed good reactivity in aprotic polar solvents such as N,N-dimethylformamide (DMF) and N-methylpyrrolidone. In reactivity MPTO resembles

Glycan recognition is typically studied using free glycans, but glycopeptide presentations represent more physiological conditions for glycoproteins. To facilitate studies of glycopeptide recognition, we developed Glyco-SPOT synthesis, which enables the parallel production of diverse glycopeptide libraries at microgram scales. The
