As a common heterocyclic compound, it belong benzodioxans compound,2,3-Dihydro-1,4-benzodioxine-6-carboxylic acid,4442-54-0,Molecular formula: C9H8O4,mainly used in chemical industry, its synthesis route is as follows.,4442-54-0
General procedure: Respective benzoic acid derivatives 5-chloro-2-methoxybenzoic acid or 13a-h (1 eq) were dissolved in anhydrous DMF, then EDCI (1.5eq), HOBT (1.5 eq) and DIEA (2.0 eq) were added successively. After the mixture was stirred at room temperature for 0.5?1h, the respective amine derivatives 3, 6 or 10 (1 eq) were added. The reaction mixture was stirred at room temperature overnight (or 12h). After the TLC showed the disappearance of the starting materials, water was added and the resulting suspension was filtered using a buchner funnel, and the precipitate was washed with water and then dried to give white solid powder. Products were further purified by flash column chromatography.
With the synthetic route has been constantly updated, we look forward to future research findings about 2,3-Dihydro-1,4-benzodioxine-6-carboxylic acid,belong benzodioxans compound
