Application of 58313-23-8, 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. 58313-23-8, name is Ethyl-3-iodobenzoate belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Example 83(IS, 2R) and (1R, 2S)-3-(2-(4-chlorophenyl)-2′-oxospiro[cyclopropane-l,3′-indoline]- l’-yl)benzoic acidSynthesis of (IS, 2R) and (1R, 2S)-methyl-3-(2-(4-chlorophenyl)-2′-oxospiro[cyclopropane- 1 ,3′-indoline] – 1 ‘-yl)benzoateA Schlenk tube was charged with Cul (9.6 mg, 0.05 mmol, 5.0 mol %), racemic (1R, 2S) and (IS, 2R)-2-(4-chlorophenyl)spiro[cyclopropane-l,3′-indolin]-2’-one (270 mg, 1.0 mmol), and K2C03 (276 mg, 2.0 mmol), evacuated, and backfilled with argon. N, Lambda – Dimethylethylenediamine (11 mu, 0.10 mmol, 10 mol %), ethyl 3-iodobenzoate (278.8 mg, 1.01 mmol), and acetonitrile (1.5 mL) were added under argon. The Schlenk tube was sealed with a Teflon valve and the reaction mixture was stirred at 80 C for 23 hours.HPLC monitored the reaction finished. The solvent was removed under reduced pressure. The residue was purified by flash column chromatography column (gradient elution, 5-10 % ethyl acetate in petroleum ether) to give the title compound as a yellow powder (290 mg, 72 %). LC/MS m/e calcd. for C24Hi8ClN03: 403, observed (M+H)+: 404.1.
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, Ethyl-3-iodobenzoate, other downstream synthetic routes, hurry up and to see.
