Reference of 40876-98-0, The chemical industry reduces the impact on the environment during synthesis 40876-98-0, name is Sodium 1,4-diethoxy-1,4-dioxobut-2-en-2-olate, I believe this compound will play a more active role in future production and life.
General procedure: A mixture of 1a (109 mg, 0.5 mmol) and 2a (116 mg, 0.55 mmol) in DMF (1.0 mL) was stirred at 120 C for 1 h. After the usual aqueous extractive workup and column chromatographic purification process (hexanes/EtOAc, 4:1), compound 4a was obtained as pale yellow oil, 123 mg (75%). Other compounds were synthesized similarly, and the spectroscopic data of 4a fare as follows.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Sodium 1,4-diethoxy-1,4-dioxobut-2-en-2-olate, other downstream synthetic routes, hurry up and to see.
