Versuchsvorschrift

A mixture of methyl 1-{[(1R,10R,11S,16S)-3-hydroxy-1,11,15,15-tetramethyl-8,8-dioxo-8λ6-thiatetracyclo[8.8.0.02,7.011,16]octadeca-2,4,6-trien-5-yl]carbonyl}piperidine-4-carboxylate (97) (0.10 g, 0.18 mmol) and LiOH.H2O (0.10 g, 2.4 mmol) in MeOH (10 mL) and water (2.0 mL) was stirred at room temperature for 18 h. The reaction mixture was concentrated under reduced pressure and acidified with 1 M HCl. The resulting solid was collected by filtration to give 1-{[(1R,10R,11S,16S)-3-hydroxy-1,11,15,15-tetramethyl-8,8-dioxo-8λ6-thiatetracyclo[8.8.0.02,7.011,16]octadeca-2,4,6-trien-5-yl]carbonyl}piperidine-4-carboxylic acid (98) (0.06 g, 63%) as a white solid. 1H NMR (CD3OD): δ 7.29 (d, 1H), 6.97 (d, 1H), 4.43 (m, 1H), 3.70 (m, 1H), 3.58 (m, 1H), 3.36 (m, 2H), 3.26-2.96 (m, 4H), 2.62 (m, 1H), 2.24 9d, 1H), 2.10-1.16 (m, 13H), 1.09-0.99 (m, 5H), 0.90 (s, 3H), 0.88 (s, 3H). MS m/z 516 (C28H39NO6S−H+).
