Synthesis of Novel 1,4-Naphthoquinones Possessing Indole Scaffolds Using In(OTf)₃ in Solvent-Free Conditions
Novel 1,4-naphthoquinones possessing indole scaffolds were prepared by the reaction of 2-hydroxy-1,4-naphthoquinone-substituted salicylic aldehydes and indoles using In(OTf)₃ as a catalyst. The method has the advantages of simple operation, mild reaction conditions, and friendly environment.
