Abstract

The invention discloses a synthesis method of polysubstituted sulfur-containing or selenium-containing benzo[c,d]indole compounds. Firstly, 8-alkynylnaphthylamine compounds, thioether (diselenide), acatalyst and an additive are placed in a reactor, a solvent is added to the reactor until 8-alkynylnaphthylamine compounds and thioether (diselenide) are completely dissolved, then, the mixture is heated to react, after the reaction, aftertreatment is performed, and the polysubstituted sulfur-containing or selenium-containing benzo[c,d]indole compounds are obtained. The polysubstituted sulfur-containing or selenium-containing benzo[c,d]indole compounds are synthesized with a one-pot one-step method, the reaction operation is simple, intermediate separation and purification processes are reduced, the reaction condition is mild, the reaction selectivity is good, the yield is high, the substrate universality is wide, the reaction materials are simple and easy to obtain, the production cost islow, and the method is applicable to large-scale industrial production as well as small-scale laboratory preparation.

Description

technical field [0001] The present invention relates to a method for synthesizing a novel multi-substituted benzo[c,d]indole compound, in particular to the synthesis of a multi-substituted sulfur- or selenium-containing benzo[c,d]indole compound method. Background technique [0002] Aryl sulfides are an important class of functional molecules, and are important intermediates in drug synthesis and material synthesis. For example, the kinase inhibitor axitinib is a recently FDA-approved diaryl sulfide. In addition, 3-thioindole compounds are also an important class of sulfur-containing compounds, which have potential application value in anti-tumor, anti-HIV, and treatment of heart disease (Adv.Synth.Catal.2009,351,2615- 2618). [0003] Organic selenide is also a very effective anticancer active drug. It is particularly important to develop a new type of anticancer active drug under the situation that the incidence and mortality of cancer in my country are on the rise. Acc...
