Versuchsvorschrift

Step 22 (D): (2R,4R)-tert-butyl 2-((1S,2S)-2-(benzyloxycarbonyl)-1-(tert-butyldimethylsilyloxy)-3-phenylpropyl)-4-(propylsulfonyl)pyrrolidine-1-carboxylate. A solution of 130 mg (0.2 mmol) of the compound of step 22 (C) dissolved in 2 mL of methanol was treated with a solution of 240 mg (0.4 mmol) of oxone dissolved in 0.4 mL of water. After stirring at rt for 30 min, the reaction solution was partitioned between ethyl acetate and water, the organic layer was concentrated, and the crude product was purified by chromatography eluting with a gradient of 20 to 80% ethyl acetate in hexanes to provide 86 mg (64%) of the desired sulfone and 37 mg (28%) of the sulfoxide intermediate as a lower-eluting compound. 1H NMR (500 MHz, CDCl3) δ 0.06 (s, 3 H) 0.11 (s, 3 H) 0.96 (s, 9 H) 1.07 (t, J=7.32 Hz, 3 H) 1.47 (s, 9 H) 1.87 (dd, J=13.43, 6.71 Hz, 3 H) 2.03 (s, 1 H) 2.26 (t, J=12.21 Hz, 1 H) 2.38 (s, 1 H) 2.68 (s, 1 H) 2.90 (s, 2 H) 3.46 (m, 2 H) 3.75 (s, 1 H) 4.09 (m, 2 H) 4.26 (d, J=7.02 Hz, 1 H) 4.77 (m, 1 H) 4.95 (m, 1 H) 7.18 (m, 10 H) MS (ESI) (M+H−Boc)+=575.25
