Yield | Reaction Conditions | Operation in experiment |
---|---|---|
99% | D-Leucine O-benzyl ester Tosylate salt To benzyl alcohol (8.2 g) dissolved in benzene (30 mL) was added D-leucine (5.0 g) and p-toluenesulfonic acid monohydrate (8.0 g). The reaction was warmed to reflux with removal of water overnight. Once TLC indicated consumption of starting material, the reaction was cooled, and the resulting solid was filtered and washed with EtOAc to give the title compound as a white powder (14.26 g, 99%). | |
73% | A. Benzyl D-Leucinate p-Toluenesulfonate This compound was prepared in a manner corresponding precisely to that described in Part A of Example 1 for preparation of the D-alinate compound. Yield, 73%, m.p. 155-156 C. Analysis, calculated for C20 H27 NO5 S (393.50): C, 61.05; H, 6.92; N, 3.56. Found: C, 61.17; H, 6.68; N, 3.81. |
