Indigo can be converted to isatin and then to oxindole. Then, in 1866, Adolf von Baeyer reduced oxindole to indole using zinc dust.[4] In 1869, he proposed a formula for indole.[5] Certain indole derivatives were important dyestuffs until the end of the 19th century. WebReduction - Benzenoid or heterocyclic rings can be selectively reduced by the indole ring. For instance, zinc/HCl can convert indole to indoline. An acidic medium also results in this type of conversion when indole is catalyzed. Benzene ring is the only one reduced by lithium/liquid ammonia. Medicinal Uses jethro tull budapest album

WebIndole is generated by reductive deamination from tryptophan via the intermediate molecule indolepyruvic acid. Tryptophanase catalyzes the deamination reaction, during which the amine (-NH 2) group of the tryptophan molecule is removed. Final products of the reaction are indole, pyruvic acid, ammonium (NH 4+) and energy.

Webreduction of intermediate 1 before further reaction is not as important as initially reported. The reaction conditions were adjusted so that an excess of indole was used (1.6 equiv.), and these conditions proved to be quite general for a variety of indoles.5 The excess indole could be recovered after column chromatography but was not routinely ... http://www.orgsyn.org/demo.aspx?prep=CV5P0567
