A novel synthesis of 2-(cyanomethyl)benzoic esters from indanone derivatives has been established. This reaction proceeds via a deprotonation of alcohols with a chemical base, followed by a nucleophilic addition to indanones and Beckmann fragmentation. In addition, this reaction could also work under electrochemical conditions, and no external chemical bases were needed. This mild method offers a novel strategy for the late-stage functionalization of various natural alcohols.

Paragraph 0023; 0024; 0025; 0026, (2019/03/08)
The invention discloses a preparation method of a 2-aminoindan derivative. The preparation method comprises the following steps: with a 1-indanone derivative as a starting raw material, carrying out oximation reaction, and synchronously reducing carbonyl and hydroxyl oxime under the catalysis of Lewis acid such as aluminum chloride in the presence of a boron metal reducing agent, so as to obtain the 2-aminoindan derivative. The invention further provides the 2-aminoindan derivative prepared by virtue of a synthetic method and a corresponding intermediate derivative. Compared with a synthetic method of the 2-aminoindan derivative in the prior art, the synthetic method disclosed by the invention has the beneficial effects that (1) only two reaction steps are adopted, and the reaction steps are obviously less than the reaction steps in the prior art; (2) the cost is relatively low, the operation is simple and convenient, and the yield is high; and (3) the preparation method is suitable for large-scale industrial production and has relatively good application prospects.
