Synthetic Route of 876-53-9,Some common heterocyclic compound, 876-53-9, name is 1,3-Dibromoadamantane, molecular formula is C10H14Br2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Compound 1,3-dibromo-adamantane (3 g, 10 mmol) was dissolved in 30 mL of toluene, and then 250 mg ofAIBN (1.5 mmol), 7 g of tri-n-butyl tin (24 mmol), 3 g of ethyl acrylate (30 mmol) were added in order. The reaction wasrefluxed with at 110 C under nitrogen for 3 hours. The reaction solution was cooled to room temperature and was pouredinto 30 mL of 0.2M aqueous ammonia. After being stirred fully, the organic layer was separated. The aqueous layerswere extracted with ethyl acetate (20 mL34). The organic layers were combined and washed with 30 mL of water and30 mL of saturated sodium chloride solution. The resulting materials were dried with anhydrous sodium sulfate, andsolvent was evaporated under the reduced pressure to give a crude product as a colorless oil, which was separated bysilica column chromatography (petroleum ether : ethyl acetate = 10:1) to give compound NM-011a as a colorless oil (2g, 46.6%). ESI-MS: mlz 337.4 ([M+H]+). 1H-NMR (DMSO-d6, ppm): 1.11 (s, 2 H), 1.15-1.19 (m, 6 H), 1.28-1.39 (m, 12H), 1.53 (s, 2 H), 1.97 (s, 2 H), 2.19-2.24 (m, 2 H), 4.03 (q, 4 H, J=7.1 Hz).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1,3-Dibromoadamantane, its application will become more common.
