Reaction Conditions:
with 1,10-Phenanthroline;copper diacetate;trifluoroacetic acid in water at 70; for 4 h;Reagent/catalyst;Temperature;Solvent;
Steps:
1-20 Example 8
General procedure: A 100 mL flask was prepared, and 0.531 g of 5-bromo-4-pentynoic acid (3.0 mmol) was dissolved in 36 mL of TFA, and after stirring, 0.162 mL of water (9.0 mmol) and 0.060 g of copper acetate monohydrate (0.30 mmol) were added. , 0.027 g of 1,10-phenanthroline (0.15 mmol), heated to 70 ° C for 4 h, the solvent was evaporated under reduced pressure and purified by column chromatography eluting with ethyl acetate / petroleum ether = 1:3 The adsorbent was washed with an adsorption column to obtain 0.544 g of 5-bromolevulinic acid in a yield of 93%.
