| Application: | Acetic acid can be used as a catalyst: • For the solvent-free one-pot condensation of indoles with aryl or heteroaryl aldehydes to synthesize di(indolyl)methanes. • In the Pictet-Spengler reaction of substituted tryptamines with cyclic ketones to synthesize tetrahydrospiro-Ͱ-carboli • To synthesize trisubstituted thiazoles via domino multicomponent reaction. It can also be used as a: • solvent to synthesize aryl amine-functionalized 1,3,5-triazine derivatives via aryl amination of cyanuric chloride with aromatic amines. |
