With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.149554-03-0,tert-Butyl 2-(4-oxopiperidin-1-yl)acetate,as a common compound, the synthetic route is as follows.
149554-03-0, [000627] A solution of Example 1.2.7 (0.055 g,), fert-butyl 2-(4-oxopiperidin-l-yl)acetate (0.014 g) and sodium triacetoxyborohydride (0.019 g) was stirred in dichloromethane (0.5 mL) at room temperature. After stirring for 2 hours, trifluoroacetic acid (0.5 mL) was added to the reaction, and stirring was continued overnight. The reaction was concentrated, dissolved in N,N- dimethylformamide (1.5 mL) and water (0.5 mL) and purified by reverse phase HPLC using a Gilson system, eluting with 10-80% acetonitrile in water containing 0.1% v/v trifluoroacetic acid. The desired fractions were combined and freeze-dried to provide the title compound. NMR (501 MHz, dimethyl sulfoxide-^) delta ppm 12.85 (s, 1H), 8.80 (s, 2H), 8.03 (d, 1H), 7.80 (d, 1H), 7.62 (d, 1H), 7.55-7.41 (m, 3H), 7.36 (q, 2H), 7.29 (s, 1H), 6.96 (d, 1H), 4.96 (s, 2H), 4.07 (s, 2H), 3.89 (t, 2H), 3.83 (s, 2H), 3.66-3.55 (m, 4H), 3.30 (s, 1H), 3.08 (s, 4H), 3.02 (t, 2H), 2.22 (d, 2H), 2.10 (s, 3H), 1.97-1.78 (m, 2H), 1.44 (s, 2H), 1.31 (q, 4H), 1.20-0.96 (m, 6H), 0.87 (s, 6H). MS (ESI) m/e 887.3 (M+H)+.
149554-03-0 tert-Butyl 2-(4-oxopiperidin-1-yl)acetate 53407149, apiperidines compound, is more and more widely used in various fields.
