Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 58313-23-8, name is Ethyl-3-iodobenzoate, A new synthetic method of this compound is introduced below., COA of Formula: C9H9IO2
Synthesis of (1S,2R) and (1R,2S)-methyl-3-(2-(4-chlorophenyl)-2′-oxospiro[cyclopropane-1,3′-indoline]-1′-yl)benzoate A Schlenk tube was charged with CuI (9.6 mg, 0.05 mmol, 5.0 mol %), racemic (1R,2S) and (1S,2R)-2-(4-chlorophenyl)spiro[cyclopropane-1,3′-indolin]-2′-one (270 mg, 1.0 mmol), and K2CO3 (276 mg, 2.0 mmol), evacuated, and backfilled with argon. N,N’-Dimethylethylenediamine (11 muL, 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 C24H18ClNO3: 403, observed (M+H)+: 404.1.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
