PROCEDURE

实验过程

The procedure described for 5c was used. Deprotection of 5a and coupling with Mtr-Glu(OEt)-OH (prepared from Fmoc-Glu-OtBu, ethanol and Mtr-chloride according to the procedure described for 51a) yielded after purification the title compound (76%) as a mixture of diastereomers (1:1). 1H-NMR 400 MHz (CD3OD) δ: 1.15-2.32 (11H, m), 2.13 (3H, s), 2.40 and 2.42 (3H, 2× s), 2.44 and 2.47 (3H, 2× s), 2.75-4.08 (11H, m), 4.99-5.19 (1H, m), 6.71 and 6.72 (1H, 2× s), 7.16-7.20(1H, m), 7.51-7.76 (3H, m), 8.30-8.36 (1H, m).
