The mol-ecules of the title compound, C(10)H(10)N(4)S, are linked by N-H(indole)⋯S hydrogen bonds to form a linear hydrogen-bonded chain. There are two independent mol-ecules in the asymmetric unit.
A stereospecific palladium-catalyzed N-vinylation of azaheterocycles with vinyl triflates is described. Cyclic and acyclic vinyl triflates along with nonnucleophilic azaheterocycles were found to be substrates for this palladium-catalyzed synthesis of N-vinyl pyrrole and indole derivatives.
Intramolecular N-arylation of pyrrole and indole carboxamides and carboxylates linked with a pendant haloarene by Cu-catalyzed reactions to synthesize pyrrole and indole quinoxalinone and oxazinone derivatives is reported. The ring closure reactions were carried out by conventional heating and MW irradiation. The use of conventional heating affords moderate to good yields of the quinoxalinone a...
A simple and efficient method for the synthesis of biologically relevant 5H-benzo[4,5][1,3]thiazino[3,2-a]indoles and 5,7-dihydroisothiochromeno[3,4-b]indoles has been developed via intramolecular copper catalysed Ullmann-type C-N coupling and palladium catalysed direct arylation from the corresponding precursors 2-(2-bromobenzylthio)-1H-indole and 2-(2-bromobenzylthio)-1-methyl-1H-indole, resp...
Reaction (1) has been studied in some detail in extracts from Neurospora crassa.6 This reaction requires the presence of pyridoxal phosphate. Further studies demonstrated that extracts from wild type N. crassa also catalyze reactions (2) and (3), and suggested that InGP is converted to tryptophan by wild type N. crassa without the formation of free indole.2 3 While a majority of N. crassa auxot...
The first enantioselective total synthesis of a member of the okaramine family of bis-indole alkaloids, okaramine N (1), has been accomplished via intermediates 2-7, as outlined. The N-prenylated derivative of (S)-tryptophan methyl ester (2) was coupled with Fmoc-protected N-tert-prenylated tryptophan (3) to form the amide 4 in 70% yield. Pd(II)-mediated cyclization/rearrangement, a key step in...
We present a combination of time-dependent density functional theory with the quantum mechanical/molecular mechanical approach which can be applied to study nonadiabatic dynamical processes in molecular systems interacting with the environment. Our method is illustrated on the example of ultrafast excited state dynamics of indole in water. We compare the mechanisms of nonradiative relaxation an...
The modification of conjugated organic compounds with organometallic moieties allows the modulation electronic and optoelectronic properties such lends them to a variety material applications. complexes [M(Cp′)(L)n] (M=Ru or Fe; Cp′=cyclopentadiene (Cp) pentamethylcyclopentadiene (Cp*); (L)n=(PPh3)2 1,2-bi(diphenylphosphino)ethane (dppe)) [M(L)n] (M=Ru; (L)n=(dppe)2 (P(OEt)3)4; M=Pt; (L)n=(PEt3...
Efficient one-pot synthesis of indol-3-yl-glycines via uncatalyzed Friedel-Crafts reaction in water.
The three component reaction of primary aliphatic amines, glyoxalic acid and indole or N-methylindole in water at ambient temperature affords indol-3-yl or N-methylindol-3-yl-glycine in almost quantitative yields.
