Descrizione generale

Acetyl bromide effectively mediates Nazarov cyclization of a cross-conjugated pentadienone to give (±)-methyl rocaglate. It is added to dissolve Arabidopsis lignin during acetyl bromide method for rapid microscale determination of lignin content in Arabidopsis.

Applicazioni

Acetyl bromide can be used:
  • In the quantification of lignin in cell wall residues of Arabidopsis.
  • In the total synthesis of cinchona alkaloids named quinidine and quinine.
  • To prepare 9,10-diarylanthracenes and triarylmethanes by reacting with arenes and various aromatic aldehydes using ZnBr2/SiO2.
  • To prepare glycosyl bromides from free sugars or their peracetates.
