Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about Asymmetric construction of polycyclic indole derivatives with different ring connectivities by an organocatalysis triggered two-step sequence.COA of Formula: C10H9NO2.

An organocatalysis triggered highly regio- and stereoselective two-step sequence between hemiacetals and indole-containing nitroolefins was developed. The key to the success of this sequence was the intramol. oxocarbenium ion induced collective alkylation at the C3, C2, or N1-position of the indole moiety, resp., providing biol. important polycyclic indole derivatives with different ring connectivities. An unexpected epimerization was observed during the C3-alkylation process, which generated products with different relative configurations compared with the C2- and N1-alkylation products.

In some applications, this compound(21778-81-4)COA of Formula: C10H9NO2 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about Amide-Amine Replacement in Indole-2-carboxamides Yields Potent Mycobactericidal Agents with Improved Water Solubility, the main research direction is methylamine carboxamide benzothiophene benzoselenophene preparation antimycobacterial lipophilicity.Related Products of 21778-81-4.

Indolecarboxamides are potent but poorly soluble mycobactericidal agents. Here, it was found that modifying the incipient scaffold by amide-amine substitution and replacing the indole ring with benzothiophene or benzoselenophene led to striking (10-20-fold) improvements in solubility Potent activity could be achieved without the carboxamide linker but not in the absence of the indole ring. The indolylmethylamine, N-cyclooctyl-6-trifluoromethylindol-2-ylmethylamine (MIC90Mtb 0.13μM, MBC99.9Mtb 0.63μM), exemplifies a promising member that is more soluble and equipotent to its carboxamide equivalent It is also an inhibitor of the mycolate transporter MmpL3, a property shared by the methylamines of benzothiophene and benzoselenophene.

Author is Gore, Vivek; Chourey, Shishir; Ye, Qiuji; Patel, Pranav; Ouedraogo, Yannick; Gravel, Sylvie; Powell, William S.; Rokach, Joshua.

5-Oxo-ETE is the most potent eosinophil chemoattractant among lipid mediators. We have developed two 5-oxo-ETE receptor antagonists. In the course of the work, we have developed a procedure to selectively introduce a cis and trans double bond in an alkyl side chain. Reacting indolecarboxaldehydes with alkyl ylides using the Li base affords the trans olefins, whereas using the K base yields the cis olefins.

An efficient one-step synthesis of 2-amino-5H-pyrimido[5,4-b]indoles through a copper-catalyzed cascade reaction between 3-haloindole-2-carbaldehydes and guanidine hydrochloride is described. In contrast, the base-mediated reactions of either 3-haloindole-2-carbaldehydes or substituted indole-2-carbaldehydes with substituted amidine hydrochlorides in DMSO result in the formation of 2-(1,3,5-triazin-2-yl)-1H-indole derivatives in one step in excellent yields. Studies toward exploring the utility of the method demonstrate that even substituted benzaldehydes undergo a similar reaction to efficiently yield 2,4,6-trisubstituted 1,3,5-triazines. A plausible mechanism for the formation of substituted 1,3,5-triazines identifies the role of DMSO as an oxidant during the reaction.

Author is Bandini, Marco; Melloni, Alfonso; Piccinelli, Fabio; Sinisi, Riccardo; Tommasi, Simona; Umani-Ronchi, Achille.

(2-Indolylmethylamino) or (3-indolylmethylamino)butadienyl carbonates such as I and a (pyrrolylmethylamino)butadienyl carbonate undergo enantioselective intramol. allylic alkylation reactions in the presence of tris(dibenzylideneacetone)palladium and nonracemic (diphenylphosphinobenzoyl)diamines such as II to yield nonracemic tetrahydro-β-carbolines, tetrahydro-γ-carbolines, and a pyrrolopyridine such as III (R = PhCH2) and IV (R = PhCH2) in 82-97% ee. (indolylmethylamino)butadienyl or (pyrrolylmethylamino)butadienyl carbonates such as I are prepared from indolecarboxaldehydes by imine formation and reduction, alkylation of the amines with bromobutenoate esters (or a bromobutenal), reduction of the ester or aldehyde with diisobutylaluminum hydride, and acylation with Me chlorocarbonate. A variety of ligands for the cyclocondensation are tried; diphenylphosphinobenzamides such as II give carbolines with the highest regioselectivities and enantioselectivities of the ligands tried. (indolylmethylamino)butadienyl carbonates substituted either on the indole or the butenyl moieties yield carbolines with similar enantio- and regioselectivities. An (E)-3-indolylmethylaminobutenol carbonate undergoes regio- and enantioselective allylic alkylation to yield a γ-carboline in 90% yield and 93% yield, while intramol. allylic alkylation of the corresponding (Z)-3-indolylmethylaminobutenol carbonate yields the opposite enantiomer in 65% yield and in 5% ee. The absolute configuration of III (R = PhCH2) is determined by X-ray crystallog. anal. of a β-carboline (-)-camphorsulfonamide derived from its enantiomer [the minor stereoisomer generated in the allylic alkylation which yields III (R = PhCH2)].
