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
