In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 5164-76-1, name is Dimethyl pent-2-enedioate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 5164-76-1

General procedure: The crude aryl diazonium tosylate 9 thus obtained was dissolved or suspended in MeOH (30 mL). Dimethyl glutaconate (1.45 mL, 10.0 mmol) and Pd(OAc)2 (112 mg, 0.5 mmol) were successively added while stirring. After stirring at r.t. for 15 h, the mixture was concentrated under reduced pressure and partitioned between CH2Cl2 (40 mL) and H2O (25 mL). The organic layer was washed with brine, dried (Na2SO4), and concentrated in vacuo. The residue was briefly fractionated on SiO2 using CH2Cl2 or CH2Cl2- acetone (5:1) as eluent. Fractions containing arylation product were pooled and concentrated to give compound 10 of at least 90% purity (according to 1H NMR analysis). It was used in the next step without further purification.

The synthetic route of 5164-76-1 has been constantly updated, and we look forward to future research findings.
