In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 707-07-3 as follows. COA of Formula: C10H14O3
General procedure: To a stirred solution of the respective N-carbamate-protected aminovicinal diol 4 (0.50 mmol, 1 equiv) in CH2Cl2 (10 mL, 0.05 M) were added BF3¡¤OEt2 (50 muL, 0.050 mmol, 0.1 equiv, 1.0 M solution in CH2Cl2) and trimethyl orthobenzoate (0.13 mL, 0.75 mmol, 1.5 equiv) at r.t. The resulting mixture was refluxed or stirred at r.t. under N2 until TLC showed complete conversion of the substrate. The reaction was quenched with sat. aq NaHCO3 and extracted with EtOAc (2 ¡Á). The combined organic layers were washed with brine, dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (hexane/EtOAc) to give the desired product 5.
According to the analysis of related databases, 707-07-3, the application of this compound in the production field has become more and more popular.
