Di-5-X-indol-3-yl disulfides (X = H 1, F 2, Br 3, I 4, OCH3 5) were synthesized and their solid state structures were probed by 13C CP/MAS NMR spectroscopy. All disulfides adopt a layered conformation and both indole rings in one molecule were assumed to have very similar structural parameters, which is in agreement with a simple spectral pattern. For compounds 1 and 5 X-ray diffraction results are also presented. In the crystals of 1 and 5, the packing of the molecules is stabilized by dissimilar weak intermolecular interactions: in 1 dominate the N1-H1?π intermolecular hydrogen bonds and in 5 the C2-H2?O10 intermolecular hydrogen bonds predominate. The di-5-fluoroindol-3-yl disulfide 2 and di-5-iodoindol-3-yl disulfide 4 were found to reduce considerably the growth of prostate cancer cell PC-3.

Nickel or iron salts catalyzing the selective synthesis of 3,3-indolyl disulfide (diselenide) and 3,3-indolyl thioether (selenide) directly from indole through C?H activation are reported. The effect of iodine element was beneficial in the novel metal-catalyzed circulation system. A wide variety of functional groups could be tolerated under the reaction conditions.

An efficient and practical strategy for the synthesis of new 3-(arylthio)indoles and related compounds has been developed, involving cleavage of readily available protected 3,3′-dithiobisindoles with metalated aromatics or heterocycles. Georg Thieme Verla
New routes to 3-(arylthio)indoles: Application to the synthesis of the 3,3′-bis(indoyl) sulfone core of the marine alkaloid echinosulfone A

A new approach to 3-(arylthio)indoles and related compounds has been developed, based on the reactions of aryl Grignard reagents or lithiated heteroaromatics with a phenylsulfonyl-protected 3,3′-bis(indolyl) disulfide. In addition, a rational approach to
Derivatives of 3-Mercaptoindole - Synthesis of a Potent Vasoconstrictor, 3-(2-Imidazolin-2-ylthio)indole (Tinazoline)

Indoles are oxidatively coupled with various cyclic and acyclic thioureas using iodine to give rise to 3-(2-imidazolin-2-ylthio)indole, 1-30, 32 and 36-40.Similar products 33, 34 and 35 are respectively obtained from benzindole, 1,6,6-trimethyl-4,5,6,7-tetrahydroindole and 7-azaindole, while alkylation of 3-mercaptoindole 44 with chlormethyl imidazoline leads to 31.Among the products so obtained, 3-(2-imidazolin-2-ylthio)indole is a potent vasoconstrictor and the hydrochloride salt forms the active ingredient of VarsylR. 3-Mercaptoindole (44) readily obtained by alkali treatment of S-(3-indolyl)isothiourea (36) is converted into amine derivatives 47 and 52 and to the acids 53-55.Acid-catalysed cyclisation of 55 affords the expected thiopyranone (57), as well as the interesting isomeric ketone (58).A mechanism is proposed for this novel rearrangement. 3-Mercaptoindole (44) is also converted to α-methylaminoacid (64) via the hydantoin (63). 3-Mercaptoindole-2-carboxylic acid (65) obtained from 10 is transformed to a variety of methylated derivatives 66-72.The amino acid 75 arising by the action of ethylenimine on 65 is esterified to 76 and cyclised to the condensed thiazepinone (77).
