Spatial separation of state- and size-selected neutral clusters [PDF]
Phys. Rev. A 86, 033202 (2012), 2012 We demonstrate the spatial separation of the prototypical indole(H2O) clusters from the various species present in the supersonic expansion of mixtures of indole and water. The major molecular constituents of the resulting molecular beam are H2O, indole, indole(H2O), and indole(H2O)2. It is a priori not clear whether such floppy systems are amenable to

HBF4 Catalysed Nucleophilic Substitutions of Propargylic Alcohols [PDF]
, 2015 The activity of HBF4 (aqueous solution) as a catalyst in propargylation reactions is presented. Diverse types of nucleophiles were employed in order to form new C–O, C–N and C–C bonds in technical acetone and in air.

Proton transfer in histidine-tryptophan heterodimers embedded in helium droplets [PDF]
Journal of Chemical Physics 142, 114306 (2015), 2015 We used cold helium droplets as nano-scale reactors to form and ionize, by electron bombardment and charge transfer, aromatic amino acid heterodimers of histidine with tryptophan, methyl-tryptophan, and indole. The molecular interaction occurring through an N-H...N hydrogen bond leads to a proton transfer from the indole group of tryptophan to the ...

Regioselective Reaction of 2-Indolylmethanols with Enamides
Molecules, 2023 A highly regioselective reaction of 2-indolylmethanols with enamides has been developed at room temperature by using AlCl3 as a catalyst. A wide range of hybrids (40 examples) of indoles and enamides were obtained in moderate to good yields (up to 98 ...

Degradation of substituted indoles by an indole-degrading methanogenic consortium [PDF]
Applied and Environmental Microbiology, 1991 Degradation of indole by an indole-degrading methanogenic consortium enriched from sewage sludge proceeded through a two-step hydroxylation pathway yielding oxindole and isatin. The ability of this consortium to hydroxylate and subsequently degrade substituted indoles was investigated.

The madelung synthesis of dihydro-1H-pyrrolo- and tetrahydropyrido[1,2-a]- indoles under mild conditions [PDF]
, 1985 Benzeneacetonitriles substituted with lactam moieties in the ortho-position cyclize under the influence of a base, dependent on the ring-size of the lactam function, to dihydropyrrolo-, tetrahydropyrido[1,2-a]indole or dihydro-1-benzazepin derivatives ...

Focus on chirality of HIV-1 non-nucleoside reverse transcriptase inhibitors [PDF]
, 2016 Chiral HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) are of great interest since one enantiomer is often more potent than the corresponding counterpart against the HIV-1 wild type (WT) and the HIV-1 drug resistant mutant strains.
