Adding a certain compound to certain chemical reactions, such as: 145576-28-9, name is Ethyl 4-methylenecyclohexanecarboxylate, belongs to esters-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 145576-28-9, COA of Formula: C10H16O2
General procedure: The alkene (1.16 mmol, 1 equivalent) was dissolved in a vigorously stirred mixture of DCM (7 mL) and acetonitrile (7 mL) under nitrogen. 2,6-Lutidine (0.27 mL, 2.32 mmol, 2 equivalents), water (10.5 mL) and sodium periodate (993 mg, 4.64 mmol, 4 equivalents) were then added sequentially. The reaction concentration with respect to the alkene was 0.047 M in a mixture of 1: 1: 1.5 – DCM: acetonitrile: water. To the resulting mixture a stock solution of ruthenium(III) chloride trihydrate (0.035 M in water) (1.16 mL, 0.04 mmol, 3.5 mol %) was added dropwise via a syringe forming a brown suspension. The reaction was stirred vigorously at 20 C for 1 h (or for the time indicated in the Tables 2 and 3). The reaction was diluted with water (20 mL) then extracted with DCM (3 x 20 mL). The organic extracts were combined then washed with brine (20 mL), passed through a phase separating cartridge and the volatiles were removed under reduced pressure. The resulting residue was purified by flash silica chromatography (EtOAc / heptane) to afford the ketone.
