Reaction Steps

A 25 mL screw top vial was charged with tert-butyl((3S,7R,8R,9S)-9-methyl-7-(4-methylbenzyl)-2-oxo-8-phenoxyoxonan-3-yl)carbamate (300 mg, 0.642 mmol), anhydrous CH2Cl2 (4 mL), and 4.0 M HCl in dioxane (3.21 mL, 12.83 mmol). After stirring at room temperature for 80 min, the reaction mixture was concentrated under a stream of nitrogen and dried under high vacuum to provide the title compound as a beige solid (259 mg, 100%): mp 200-210° C. (dec.); 1H NMR (400 MHz, CDCl3) δ 7.46-6.81 (m, 9H), 5.14 (s, 1H), 3.78-3.52 (m, 3H), 2.86 (s, 1H), 2.60-1.12 (m, 12H), 0.96 (s, 1H); 13C NMR (101 MHz, CD3OD) δ 171.05, 160.65, 137.89, 136.19, 130.75, 129.87, 129.75, 122.14, 117.03, 81.89, 76.55, 68.05, 46.67, 37.46, 32.38, 27.71, 21.05, 20.12, 18.85; ESIMS m/z 369 ([M+H]+).
