Synthetic Route of 105-53-3, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 105-53-3 name is Diethyl malonate, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a suspension of sodium hydride (900 mg, 37.5 mmol) indry THF (30 mL), diethyl malonate 6a (2 g, 12.5 mmol) was added and the reaction mixturewas stirred at r.t. for 10 min. Later, allyl bromide (1.30 mL, 14.80 mmol) was added and thestirring was continued for 12 h at same temperature. At the conclusion of the reaction (TLCmonitoring), the reaction mixture was diluted with EtOAc and the aqueous layer wasextracted with CH2Cl2. Then, the solvent was removed under reduced pressure and the crudeproduct was purified by silica gel column chromatography (2% EtOAc-petroleum ether) toafford the mono-allylated compound 13a as a thick colourless liquid (1.52 g, 63%) along withdi-allylated compound 14a as a thick colourless liquid (693 mg, 24%). The 1H and 13C NMRspectra matched with the literature reported spectral data.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Diethyl malonate, and friends who are interested can also refer to it.
