Brief introduction of 496-16-2

496-16-2, 496-16-2 2,3-Dihydrobenzo[b]furan 10329, abenzofuran compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.496-16-2,2,3-Dihydrobenzo[b]furan,as a common compound, the synthetic route is as follows.

Chlorination using NCS has been found to be applicable for use with a wide range of aromatic starting materials or substrates, as is shown in Table 2. All the substrates treated with 1 equivalent of NCS and 5 mole % of ZrCU afforded the corresponding chlorinated compounds. The reaction at room temperature afforded a high yield of chlorinated product with high regioselectivity. In some cases, a small amount of regioisomers (Entry 3) or dichlorinated products (Entries 4 and 5) were observed.Table 2 ZrCIj Catalyzed Chlorination of Aromatic Compounds by NCS2-CI : 4-CI (13: 87)b EPO 1 -CI : 1 ,4-di-CI(83: 17)ba Reaction conditions. Substrate (0.5 mmol), NCS (0.5 mmol), ZrCI4 (5 mol %), CH2CI2 (4 mL). b Determined by 1H NMR. c See spectroscopic data for characterization.
