Electric Literature of 1829-28-3, A common heterocyclic compound, 1829-28-3, name is Ethyl 2-iodobenzoate, molecular formula is C9H9IO2, 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.
General procedure: A dry and argon-flushed Schlenk tube, equipped with a magnetic stirring bar and a rubber septum was charged with Ni(acac)2 (12.8 mg, 0.05 mmol, 0.05 equiv) as catalyst, 4-fluorostyrene (24.4 mg, 0.20 mmol, 0.20 equiv), the aryl iodide or heteroaryl chloride 3 as electrophile (1.00 mmol, 1.00 equiv), and freshly distilled THF (1 mL). The resulting suspension was cooled to 0 °C and the prior prepared benzylic manganese chloride solution (1.20 mmol, 1.20 equiv) was added dropwise at the prior adjusted temperature. The reaction conversion was monitored by GC analysis of hydrolyzed aliquots. After full conversion of the selected electrophile, the reaction mixture was quenched with a sat. aq NH4Cl and extracted with EtOAc (3 × 75 mL). The combined organic layers were dried (MgSO4), filtered, and concentrated under reduced pressure. Purification of the crude product by flash column chromatography afforded the desired products.
The synthetic route of 1829-28-3 has been constantly updated, and we look forward to future research findings.
