Procedure details
To a solution of benzyl 2-p-isobutylphenylpropionate (3 g) in methylene chloride (18 ml) are added a solution of aluminum chloride (4 g) in nitromethane (50 ml) and anisole (3 ml) at 0° C., and the mixture is stirred at room temperature for 6 hours. The reaction mixture is diluted with ethyl acetate, washed with hydrochloric acid and water, dried and evaporated. The residue is recrystallized with n-hexane to give 2-p-isobutylphenylpropionic acid (186 mg) melting at 75°-77.5° C. Yield 91%.

Open Reaction Database (ORD) |
|
Description
|
The Open Reaction Database (ORD) is an open-access schema and infrastructure for structuring and sharing organic reaction data, including a centralized data repository. The ORD schema supports conventional and emerging technologies, from benchtop reactions to automated high-throughput experiments and flow chemistry. Our vision is that a consistent data representation and infrastructure to support data sharing will enable downstream applications that will greatly improve the state of the art with respect to computer-aided synthesis planning, reaction prediction, and other predictive chemistry tasks. |
