N-CARBOBENZOXY-L-SERINE BETA-LACTONE Use and Manufacturing
Standard Procedure for the Synthesis of Ddz-Dap(Boc-Me)-OH (Ddz-AA4, FIG. 2); Step 4-1. Z-Serine-β-lactone (AA4-2).; This intermediate was prepared in an analogous fashion to that described previously for the Boc derivative AA3-1. In a dry 250 mL 3-neck flask equipped with a mechanical stirrer under nitrogen atmosphere was added triphenylphosphine (4.5 g, 17.1 mmol, 1.1 eq.), followed by 100 mL of an anhydrous THF:CHa
