Versuchsvorschrift

(S)-2-(tert-butoxycarbonyl)-3-(2-nitro-N-(pent-4-enyl)phenylsulfonamido)propanoic acid (1.10 g, 2.40 mmol) dissolved in 20 mL of DCM was treated sequentially with 1-{[4-(isoquinolin-1-yloxy)-pyrrolidine-2-carbonyl]-amino}-2-vinyl-cyclopropanecarboxylic acid ethyl ester, bis hydrochloride (1.27 g, 2.72 mmol), N-methyl morpholine (0.92 mL, 8.34 mmol), and HATU (PE biosystems)(1.28 g, 3.36 mmol). The reaction mixture was stirred at rt under N2 for 15 h, and then concentrated in vacuo. The residue was partitioned between ethyl acetate and pH 4 buffer (biphthalate). The organic phase was washed with sat. aq. NaHCO3, dried (MgSO4), and concentrated in vacuo to give 2.0 g of the crude product. Flash chromatography (30% hexane/ethyl acetate) gave 1.4 g (70%) of (1R,2S)-ethyl 1-((3R,5S)-1-((S)-2-(tert-butoxycarbonyl)-3-(2-nitro-N-(pent-4-enyl)phenylsulfonamido)propanoyl)-3-(isoquinolin-1-yloxy)pyrrolidine-5-carboxamido)-2-vinylcyclopropanecarboxylate as a purple solid. 1H NMR (CD3OD, 500 MHz) δ 1.23–1.31 (m, 9H), 1.46–1.52 (m, 4H), 1.59 (br s, 1H), 1.66 (br s, 1H), 1.74 (dd, J=7.93, 5.19 Hz, 1H), 2.00 (br s, 2H), 2.29 (q, J=8.95 Hz, 1H), 2.47 (m, 1H), 2.72 (m, 1H), 3.38–3.51 (m, 2H), 3.68 (m, 2H), 4.09–4.26 (m, 3H), 4.37 (d, J=11.29 Hz, 1H), 4.64 (m, 1H), 4.72 (m, 1H), 4.95 (d, J=10.99 Hz, 1H), 4.99 (dd, J=18.92, 1.53 Hz, 1H), 5.12 (d, J=10.68 Hz, 1H), 5.32 (d, J=17.40 Hz, 1H), 5.73–5.86 (m, 2H), 5.92 (s, 1H), 7.36 (m, 1H), 7.58 (m, 1H), 7.73 (m, 1H), 7.80–7.88 (m, 4H), 7.99 (m, 1H), 8.11 (m, 1H), 8.24 (d, J=8.24 Hz, 1H).
