Reaction Steps

The procedure described for 5c was used. Deprotection of Sa and coupling with (2S)-3-hydroxy-2-[(2-naphthalenylsulfonyl)amino]propanoic acid (prepared from L-serine and 2-naphthalenylsulfonylchloride using the procedure described for 5b) yielded 7. 1H-NMR 200 MHz (CD3OD) δ: 1.12-1.58 (6H, m), 2.57-2.69 (1H, m) 2.95-3.95 (8H, m), 4.9-5.1 (1H, m), 7.11-7.22 (1H, m), 7.43-8.16 (9H, m), 8.24-8.34 (1H, m), 8.41-8.45 (1H, m).
