Darzens synthesis of 2,2-dichloro-3-(2-furyl)-3-hydroxypropionic acid derivatives
摘要:
Esters and amides of 2,2-dichloro-3-(2-furyl)-3-hydroxypropionic acid were prepared by the reaction of furfural with dichloroacetic acid derivatives under the conditions of the Darzens condensation. The structures of the reaction products were confirmed by their H-1 NMR and IR spectra and chemical transformations.

Dimethyl dichloromalonate reacts with aldehydes in the presence of sodium methoxide to form alpha-chloropyruvates, alpha-chloroglycidates, or alpha,alpha-dichlorohydrins depending on the nature of the aldehyde.
