Synthetic Route of 10297-05-9, These common heterocyclic compound, 10297-05-9, name is 1-Chloro-4-iodobutane, its 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.
First, 1-chloro-4-iodobutane (1.00 g, 4.57 mmol) was dissolved into a mixture solvent of diethyl ether/pentane (2:3) to obtain a concentration of 0.10 M, the resultant mixture was cooled to -78¡ã C. t-butyl lithium (3.690 g, 9.610 mmol, 1.7M solution in pentane) was added gradually to the cooled solution of 1-chloro-4-iodobutane and stirred for 2 hours. 1,5-dichloropentane-3-one (838 mg, 4.580 mmol) dissolved in diethyl ether (8 mL) was added gradually to the reaction mixture. The reaction mixture was stirred for additional 4 hours at -78¡ã C., and then ice water (50 mL) was added to quench the reaction path, followed by extraction with diethyl ether. The organic layer was collected and dried over anhydrous magnesium sulfate and filtered, the solvents were removed under reduced pressure. The obtained crude product was purified by column chromatography using silica gel (hexane:ethyl acetate=5:1) to obtain 820 mg of compound 17 (yield 65percent).1H NMR (CDCl3): delta 3.52 (t, J=6.4 Hz, 6H, CH2Cl), 1.80-1.73 (m, 6H, CH2), 1.56-1.52 (m, 4H, CH2), 1.42 (s, 4H, CH2) ppm. 13C{1H} NMR (CDCl3): delta 73.58, 45.69, 44.95, 38.29, 36.48, 32.94, 26.96, 20.88 ppm.
The synthetic route of 10297-05-9 has been constantly updated, and we look forward to future research findings.
