(1R,2S)-2-fluorocyclopropanecarboxylic acid Structural

What is (1R,2S)-2-fluorocyclopropanecarboxylic acid?

Synthesis

Dissolve benzyl alcohol and allyl bromide in the solvent, add sodium hydride, and perform a condensation reaction to obtain allyl benzyl ether. The obtained allyl benzyl ether, dichlorofluoromethane, and sodium hydroxide solution are raw materials for carbene reaction to obtain 2-chloro-2-fluorocyclopropylmethyl benzyl ether. Subsequently, the obtained 2-chloro-2-fluorocyclopropylmethylbenzyl ether is hydrogenated and reduced to obtain 2-chloro-2-fluorocyclopropanemethanol. Sodium hypochlorite is added as an oxidizing agent to perform an oxidation reaction to obtain 2-chloro-2-fluorocyclopropanecarboxylic acid. Finally, diethylamine is added to perform a hydrogenation reduction reaction to obtain (1R,2S)-2-fluorocyclopropanecarboxylic acid. (1R,2S)-2-fluorocyclopropanecarboxylic acid
