• Uses: Dysprosium(III) trifluoromethanesulfonate is a water-tolerant Lewis acid used in the Aldol reaction of silyl enol ethers with aldehydes. This is an effective catalyst for electrophilic substitution reactions of indoles with imines. Also used as catalyst for Aza-Piancatelli rearrangement, Friedel-Crafts alkylation, ring-opening polymerization reactions, microwave-assisted Kabachnik-Fields condensation, cycloaddition reactions (Lewis-acid catalyst), fries rearrangement and enantioselective glyoxalate-ene reactions.

Synthesis and cytotoxic potency of novel tris(1-alkylindol-3-yl)methylium salts: Role of N-alkyl substituents

10.1016/j.bmc.2010.07.025

The research focuses on the synthesis and cytotoxic potency of novel tris(1-alkylindol-3-yl)methylium salts. The study demonstrates an easy substitution of indole rings in trisindolylmethanes for other indoles under the action of acids and discusses the mechanism of substitution. An environmentally safe method of oxidation of trisindolylmethanes with air oxygen in acidic conditions was developed to obtain trisindolylmethylium salts. The cytotoxicity of the novel compounds increased with the number of carbon atoms in the alkyl chains, with optimal potency observed for compounds with 3–5 carbon atoms. The most potent compounds killed human tumor cells at nanomolar-to-submicromolar concentrations, being significantly more potent than the prototype antibiotic turbomycin A. Key chemicals involved in the research include tris(indol-3-yl)methanes, tris(indol-3-yl)methylium salts, N-alkylindol-3-carboxaldehydes, N-substituted indoles, acetic acid, La(OTf)3, Dy(OTf)3, methanesulfonic acid, and various other reagents used for synthesis and biological testing. The study concludes that N-alkyl substituted tris(1-alkylindol-3-yl)methylium salts are promising candidates for further development as anticancer drugs.
