Descrizione generale

2,5-Dimethylfuran is a heterocyclic furan used as a building block in organic synthesis.

Applicazioni

2,5-Dimethylfuran can be used as:
  • A reactant to prepare exo-maleimide-dimethylfuran cyclo adduct, which is used in the synthesis of oligonucleotide conjugates.
  • An arynophile to synthesize 1,4-dimethyl-1,4-dihydro-1,4-epoxynaphthalene (fused benzene) by reacting with a mixture of neopentyl glycol and 2-hydroxyphenylboronic acid in the presence of a strong base.
  • A precursor to prepare p-xylene via Diels-Alder cycloaddition and subsequent dehydration reaction.
