2-Acetoxy-2-methylpropionyl bromide Usage And Synthesis
Chemical Propertieslight yellow clear liquid
Uses1-Bromocarbonyl-1-methylethyl acetate (α-Acetoxyisobutyryl bromide) may be used:
  • in the chemoenzymatic synthesis of (1R,2S)-1,2-epoxy-1,2-dihydroacridine (acridine 1,2-oxide)
  • in the synthesis of protected 3′-deoxyadenosine and 3′-deoxyguanosine
  • as reagent for deoxygenation of vicinal diols, as well as in the preparation of 2′,3′-dideoxycytidine and other dideoxy and deoxynucleosides from the corresponding ribo series.
General Description1-Bromocarbonyl-1-methylethyl acetate (α-Acetoxyisobutyryl bromide) participates in the conversion of adenosine to trans-3′(2′)-bromo-2′(3′)-acetates, via glycosyl cleavage.
