Related Products of 6940-76-7, These common heterocyclic compound, 6940-76-7, name is 1-Chloro-3-iodopropane, 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.
A solution of ethyl 3-oxobutanoate (1.95 g, 14.98 mmol) in tetrahydrofuran (20 mL) was added dropwise to a stiired 1 M solution of lithium diisopropylamine (30 mL, 30 mmol) at-78 C. The solution was stirred for an additional hour at-78 C, and then a solution of 1-chloro-3-iodopropane (3.07 g, 15.02 mmol) in tetrahydrofuran (50 mL) was added. The resulting solution was allowed to warm to room temperature and stirred for an additional two hours. Water was added, and the mixture was extracted twice with ethyl acetate. The combined organic layers were dried (Na2SO4) and concentrated. The resulting residue was purified via MPLC eluting with a gradient of 20-50% ethyl acetate in petroleum ether to afford ethyl 7-chloro-3-oxoheptanoate (2.8 g, 90%) as an oil.
The synthetic route of 6940-76-7 has been constantly updated, and we look forward to future research findings.
