2,3-Dihydrobenzo[b][1,4]dioxine-5-carboxylic acid, cas is 4442-53-9, it is a common heterocyclic compound, the benzodioxans compound, its synthesis route is as follows.,4442-53-9
4.1.1.1. 6-Bromo-3-((2,3-dihydrobenzo[b][1,4]dioxin-5-yl)methyl)-2-methoxyquinoline (VI: Y = 2,3-O(CH2)2O-). To a solution of 2,3-dihydrobenzo[b][1,4]dioxine-5-carboxylic acid (5.00 g, 28.0 mmol)in THF (150 mL) at 0 C was added lithium aluminium hydride(2.13 g, 56.0 mmol) in small portions. The reaction mixture wasstirred at 0 C for 10 min and stirred for a further 18 h at 20 C.Water (150 mL) was added to the reaction mixture which wasextracted with EtOAc (2 100 mL). The combined organic layerswere washed with brine (100 mL), dried over Na2SO4, filteredand concentrated under reduced pressure to obtain (2,3-dihydrobenzo[b][1,4]dioxin-5-yl)methanol as a yellow oil (3.22 g,99%). 1H NMR (CDCl3, 400 MHz) d 6.87-6.79 (m, 3H), 4.66 (s, 2H),4.32-4.30 (m, 2H), 4.28-4.25 (m, 2H), 2.19 (bs, 1H). Found: [M+H-18] = 149.5.
With the rapid development of chemical substances, we look forward to future research findings about 2,3-Dihydrobenzo[b][1,4]dioxine-5-carboxylic acid
