These common heterocyclic compound, 4224-69-5, name is Methyl 2-(bromomethyl)acrylate, 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. Formula: C5H7BrO2
General procedure: To a 20 mL two-necked round-bottom flask attached with areflux condenser were added V-65 (25 mg, 0.1 mmol) and K2CO3(138 mg, 1.0 mmol), and this flask was purged with argon.Then, 1-nonanal (1a, 71 mg, 0.5 mmol), methyl 2-(bromomethyl)acrylate (2a, 269 mg, 1.5 mmol), and degassedbenzene (5 mL) were added. The mixture was stirred at 60 C for1 h. The reaction mixture was filtered through a short plug ofCelite, and the filtrate was concentrated under reduced pressure.The residue was purified by flash column chromatographyon SiO2 (hexane/EtOAc = 1:0 to 30:1) and preparative HPLC(chloroform) to give methyl 2-methylene-4-oxododecanoate(3b, 101 mg, 84%).
The synthetic route of Methyl 2-(bromomethyl)acrylate has been constantly updated, and we look forward to future research findings.
