, p. 4525 - 4527 (2012)
Copper(I)-catalyzed dearomative arylation and vinylation of 2-substituted tryptophols were realized with a subsequent cyclization reaction. The cascade dearomatization sequence provided versatile furoindoline derivatives with two quaternary carbon centers

supporting information, p. 2952 - 2956 (2017/07/24)
An environmentally friendly and efficient protocol (KX/oxone) for oxidative halocyclization of tryptamine/tryptophol derivatives was developed and demonstrated with 28 examples and concise total synthesis of cyclotryptamine alkaloid protubonines A and B. The distinct advantage of this protocol over all previous methods is that no organic byproduct is generated from a halogenating agent or oxidant, thus greatly reducing the environmental impact of halocyclization and facilitating the post-reaction purification.

In glioblastoma multiforme (GBM), translocator protein (TSPO) and murine double minute (MDM)2/p53 complex represent two druggable targets. We recently reported the first dual binder 3 possessing a higher anticancer effect in GBM cells than the standards P
Dearomatization of tryptophols via a vanadium-catalyzed asymmetric epoxidation and ring-opening cascade
Han, Long,Liu, Chuan,Zhang, Wei,Shi, Xiao-Xin,You, Shu-Li

An enantioselective epoxidation of tryptophols followed by an intramolecular epoxide opening reaction was realized by chiral vanadium catalysts derived from C2 symmetric bis-hydroxamic acid (BHA) ligands. 3a-Hydroxyfuroindoline derivatives with up to 89% yield and 90% ee were obtained under mild reaction conditions.

We report the synthesis and the affinity data at both the peripheral (PBR) and the central benzodiazepine receptors of a series of N,N-dialkyl-2-phenylindol-3-ylglyoxylamide derivatives III, designed as conformationally constrained analogues of 2-phenylin
A versatile linkage strategy for solid-phase synthesis of N,N-dimethyltryptamines and β-carbolines
Wu, Tom Y. H.,Schulte, Peter G.
, p. 4033 - 4035 (2007/10/03)
(matrix presented) Various tryptamines are captured by a vinylsulfonylmethyl polystyrene resin, generating a safety-catch linkage. β-Carbolines can be formed from 4 by a Pictet-Spengler reaction with the introduction of R1. Tryptamine 4 can also be derivatized by acylation or copper-mediated coupling to introduce R2. If X = Br, Suzuki coupling can be used to introduce R3. After derivatization, the indole derivatives are activated with methyl iodide and released under mild basic condition.
Synthesis and antiserotonin activity of ethyl 5-O-(4-methylpiperazin-1-ylacetyl)-2-methylindole-3-carboxylates and 3-(4-methyl-1-piperazinylglyoxyl)indoles
Purohit, M. G.,Badiger, G. R.,Kalaskar, N. J.
, p. 796 - 801 (2007/10/03)
Ethyl-5-O-chloroacetyl-2-methylindole-3-carboxylates (2a-e) have been synthesised by the reaction of ethyl 5-hydroxy-2-methylindole-3-carboxylates (1a-e) with chloroacetyl chloride in dry benzene containing triethylamine.These indoles (2a-e) on condensation with methylpiperazine in dry acetone in the presence of anhydrous K2CO3, afford ethyl 5-O-(4-methylpiperazin-1-ylacetyl)-2-methylindole-3-carboxylates (3a-e).Compounds 3a-e are converted into their oxalate derivatives (4a-e).Indole-3-glyoxyl chlorides (6a-e) have been prepared from appropriate indoles (5a-e) byreaction with oxalyl chloride in dry ether. these derivatives on condensation with methylpiperazine yield 3-(4-methyl-1-piperazinylglyoxylyl)indoles (7a-e) wich are converted into oxalate salts (8a-e).Compounds 4a-e and 8a-e have been screened for their antiserotonin activity.Only compound 4d is found to exhibit antiserotonin activity.
