General description
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.
Application
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.
