Reference of 4224-69-5, 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. 4224-69-5, name is Methyl 2-(bromomethyl)acrylate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
(2) To an anhydrous THF solution (2 ml) of the above-obtained Compound (8) (A=-CH=CH-CH=CH-, PG=TBS, 24(E)) (48 mg, 76.8 mumol) were added zinc (powder) (8 mg, 0.12 mmol), methyl 2-(bromomethyl)acrylate (13.8 mul, 0.12 mmol) and a saturated ammonium chloride aqueous solution (0.7 ml) at 0C, and the mixture was stirred for 30 min at room temperature. The reaction was quenched with water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and then with brine, dried over anhydrous magnesium sulfate, and concentrated. The residue was purified by column chromatography (5%?20% ethyl acetate in hexane) to obtain Compound (C) (60 mg, 107% yield). Compound (C):1H NMR (CDCl3) delta : 0.055 (s, 3 H), 0.059 (s, 3 H), 0.062 (s, 6 H), 0.55 (s, 3 H), 0.88 (s, 18 H), 1.04 (d, J=6.6 Hz, 3 H), 1.23-2.17 (m, 15 H), 2.18-2.24 (m, 1 H), 2.42-2.52 (m, 2 H), 2.60-2.65 (m, 1 H), 2.78-2.86 (m, 1 H), 3.74 (s, 3 H), 4.19-4.22 (m, 1 H), 4.28-4.34 (m, 1 H), 4.34-4.39 (m, 1 H), 4.86 (d, J=2.2 Hz, 1 H), 5.17 (s, 1 H), 5.53-5.62 (m, 1 H), 5.67 (d, J=1.2 Hz, 1 H), 5.90-6.03 (m, 2 H), 6.15-6.25 (m, 2 H), 6.26 (d, J=1.2 Hz, 1 H). MS m/z 747 (M+23)+.
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, Methyl 2-(bromomethyl)acrylate, other downstream synthetic routes, hurry up and to see.
