75% | Example 18: Preparation of 2-deoxy-2-(pent-4-enoylamino)-3-O-[4-methoxyphenyl(benzyloxy-L-alanyl)] phosphoramidate-D-glucopyranose (compound 18); 1. Preparation of 2-deoxy-2-(pent-4-enoylamino)-D-glucopyranose; To a vigorously stirred solution of NaOMe (3.2 g, 56.4 mmol) in MeOH (75 ml) was added (D)-glucosamine hydrochloride (12.1 g, 56.37 mmol). The mixture was stirred for 5 min. The precipitate NaCl was removed by filtration through Celite and the filter cake was rinsed with MeOH. The filtrate was placed in an ice bath, and pent-4-enoic anhydride (12.4 g 67.6 mmol, obtained according to P. Perlmutter et al., Org. Biomol. Chem. 2, 2220-2228 (2004); R. Madsen et al., J. Org. Chem. 60, 7920-7926 (1995)) was added immediately. Crystallization began almost instantaneously. The mixture was stirred for 10 min and then kept in the freezer overnight. Filtration gave the title compound (11.1 g, 75% yield). 1H-NMR (CD3OD, 500MHz): delta 5.83 (1H, m), 5.05 (3H, m), 3.83 (2H, m), 3.66 (2H, m), 3.45 (2H, m), 2.25 (4H, m). |
