Descrizione

Descrizione generale

Methyl dichloroacetate undergoes base-catalyzed condensation with aliphatic α-haloaldehydes. Chlorination of methyl dichloroacetate by using trifluoromethanesulfonyl chloride has been reported.

Applicazioni

Methyl dichloroacetate may be used:

• in the diastereoselctive synthesis of bicyclic chlorocyclopropane
• as difunctional initiator during atom transfer radical polymerization of methyl or n-butyl acrylate
• as reagent during CrCl₂-induced olefination of aldehydes

Reactant involved in:

• Nucleophilic substitution reactions with nitro(pentafluorosulfanyl)benzenes
• Azide-alkyl halide cycloaddition and atom transfer radical addition
• Chemical modification of STn antigen for enhancement of synthetic carbohydrate vaccines
• Three component reaction of arynes with cyclic ethers and active methines
• Catalytic radical haloalkylation for synthesis of neodysidenin
• Addition reactions for syntehsis of enantiopure 3,4-diamino esters or amides
