Methyl cyanoacetate Usage And Synthesis

Description

Methyl cyanoacetate is the intermediate product in pharmaceutical organic synthesis as well as in the synthesis of some biologically active compounds used in agriculture. It may be used in the synthesis of various 1,2,5-tricarbonyl compounds. It is often used as a nucleophile in the electrochemical oxidation of catechols. Methyl Cyanoacetate is also a reagent in the synthesis of Methyl 2-Amino-4-trifluoromethylthiophene-3-carboxylate; a compound used in the synthesis of DPP-IV inhibitors for treating type-2 diabetes. In addition, it is an intermediate in the preparation of α-cyanoacrylate, malononitrile, and 1,1-cyclohexanediacetic acid dyes. It is used as UV absorber or stabilizer, intermediate for pharmaceuticals. It may be used in the synthesis of various 1,2,5-tricarbonyl compounds.

Uses

Methyl cyanoacetate is an intermediate in the preparation of α-cyanoacrylate, malononitrile, 1,1-cyclohexanediacetic acid dye. It is used as UV absorber or stabiliser, intermediate for pharmaceuticals. It may be used in the synthesis of various 1,2,5-tricarbonyl compounds.

General Description

Methyl cyanoacetate is the intermediate product in pharmaceutical organic synthesis as well as in the synthesis of some biologically active compounds used in agriculture. It undergoes calcite or fluorite catalyzed Kn?venagel condensation with aromatic aldehydes, giving the corresponding arylidenemalononitriles and (E)-α-cyanocinnamic esters.

Purification Methods

Purify the ester by shaking with 10% Na2CO3 solution, wash well with water, dry with anhydrous Na2SO4, and distil it. [Beilstein 2 H 584, 2 I 253, 2 II 530, 2 III 1628, 2 IV 1889.]
