2,3-Dihydro-1,4-benzodioxine-6-carboxylic acid, cas is 4442-54-0, it is a common heterocyclic compound, the benzodioxans compound, its synthesis route is as follows.,4442-54-0
(1) Synthesis of Compound k (0145) A mixed solution of the compound j (1.5 g) and sulfuric acid (2.0 ml)/methanol (17 ml) was introduced into an eggplant-shaped flask and heated overnight to reflux. The reaction solution was extracted with ethyl acetate. Then, the extract was washed with saturated saline, dehydrated with sodium sulfate, and concentrated. The concentrate was purified by silica gel column chromatography (Wakosil? C-300) using hexane-ethyl acetate as an eluent. Thus, the compound k was obtained (yield: 1.69 g; yield rate: 52percent).
As the rapid development of chemical substances, we look forward to future research findings about 4442-54-0
