Three-component synthesis of 3-(diarylmethyl)indoles using Fe(ClO4)3/SiO2 as catalyst

Аннотация

Three-component reaction of indole, aromatic aldehyde, and N,N-dimethyl aniline in the presence of silica-supported Fe(ClO₄)₃ as catalyst afforded the corresponding 3-[aryl(4-dimethylaminophenyl)methyl]-indoles in excellent yields under mild conditions. The proposed protocol offers some remarkable advantages such as the use of a solid catalyst and simple workup procedure.
