Reference of 80379-31-3, Adding some certain compound to certain chemical reactions, such as: 80379-31-3, name is Ethyl 3-hydroxy-2H-chromene-4-carboxylate,molecular formula is C12H12O4, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 80379-31-3.
The mixture of 2a (44 mg, 0.2 mmol) and Ph2O (400 mg) was heated to 210 C under argon for 30 min. After cooling to the room temperature, the residue was purified on silica gel (PE/EtOAc, 30:1) to get the product as a colorless oil (25 mg, 84%). 1H NMR (400 MHz, CDCl3): delta 7.26-7.22 (m, 1H), 7.14-7.12 (m, 1H), 7.06 (d, J=7.6 Hz, 2H), 4.41 (s, 2H), 3.62 (s, 2H); 13C NMR (100 MHz, CDCl3): delta 207.74, 154.65, 129.08, 128.58, 123.45, 121.63, 117.80, 73.08, 41.03 ppm. The date of the compound is identical with the described date of the reference.16
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. 80379-31-3, Ethyl 3-hydroxy-2H-chromene-4-carboxylate, other downstream synthetic routes, hurry up and to see.
