TfNHNHBoc as a SCF3 source for the sulfenylation of indoles

An unprecedented use of trifluoromethanesulfonyl hydrazides as effective SCF3 sources has been established in the sulfenylation of indoles. A range of substituted indoles participated in CuCl-catalyzed oxidative sulfenylation reaction with TfNHNHBoc in the presence of dimethyl sulfoxide to furnish structurally diverse 3-indolyl trifluoromethyl thioethers in moderate to good yields with very high regioselectivity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: Methyl 1H-indole-5-carboxylate, you can also check out more blogs about1011-65-0

Iron(II) chloride-1,1?-binaphthyl-2,2?-diamine (FeCl 2-BINAM) complex catalyzed domino synthesis of bisindolylmethanes from indoles and primary alcohols

Biologically important bisindolylmethanes are synthesized in a domino fashion by using an iron(II) chloride-(¡À)-1,1?-binaphthyl-2, 2?-diamine [FeCl2-(¡À)-BINAM] complex as the catalyst. This method proceeds via oxidation of a primary alcohol into the corresponding aldehyde followed by nucleophilic addition of an indole in the presence of the catalyst. A reaction intermediate is synthesized separately and converted into the bisindolylmethane product under the same reaction conditions as support for the proposed mechanism.

Exploiting the Distal Reactivity of Indolyl Methylenemalononitriles: An Asymmetric Organocatalyzed [4+2] Cycloaddition with Enals Enables the Assembly of Elusive Dihydrocarbazoles

An unprecedented technique for the in situ generation of indolyl ortho-quinodimethanes from 2-methylindole-based methylenemalononitriles by amine-mediated remote C(sp3)?H deprotonation was developed. These intermediates were efficiently trapped by diverse enals to provide a rapid entry to 2,9-dihydro-1H-carbazole-3-carboxyaldehyde structures through a formal asymmetric [4+2] eliminative cycloaddition governed by a alpha,alpha-diphenylprolinol trimethylsilyl ether catalyst.

Structure-activity relationship of antiparasitic and cytotoxic indoloquinoline alkaloids, and their tricyclic and bicyclic analogues

Based on the indoloquinoline alkaloids cryptolepine (1), neocryptolepine (2), isocryptolepine (3) and isoneocryptolepine (4), used as lead compounds for new antimalarial agents, a series of tricyclic and bicyclic analogues, including carbolines, azaindoles, pyrroloquinolines and pyrroloisoquinolines was synthesized and biologically evaluated. None of the bicyclic compounds was significantly active against the chloroquine-resistant strain Plasmodium falciparum K1, in contrast to the tricyclic derivatives. The tricyclic compound 2-methyl-2H-pyrido[3,4-b]indole (9), or 2-methyl-beta-carboline, showed the best in vitro activity, with an IC50 value of 0.45 muM against P. falciparum K1, without apparent cytotoxicity against L6 cells (SI > 1000). However, this compound was not active in the Plasmodium berghei mouse model. Structure-activity relationships are discussed and compared with related naturally occurring compounds.

Palladium-Mediated Oxidative Annulation of delta-Indolyl-alpha,beta-Unsaturated Compounds toward the Synthesis of Cyclopenta[ b]indoles and Heterogeneous Hydrogenation to Access Fused Indolines

The cyclopenta[b]indole moiety represents a key skeletal unit in several natural and synthetic compounds that exhibit diverse biological properties. We described herein a two-step sequence for synthesizing cyclopenta[b]indoles with great structural diversity in overall yields up to 37%. The key step was a palladium-catalyzed oxidative annulation of 3-alkylindoles (Fujiwara-Moritani reaction). The obtained cyclopenta[b]indoles were used as substrates in heterogeneous hydrogenation reactions to afford new fused indolines in moderate yields. An acid-catalyzed intramolecular cyclization of three such indolines gave tetracyclic lactams in 89, 90, and 61% yields.

Facile synthesis of 1,4-diketones: Via three-component reactions of alpha-ketoaldehyde, 1,3-dicarbonyl compound, and a nucleophile in water

Three-component reactions of alkylglyoxals, 1,3-dicarbonyl compounds, and a nucleophile were performed under aqueous and catalyst-free conditions, which produced 1,4-diketone scaffolds in a straightforward way. Many compounds, such as indole, azaindole, pyrrole, 2-methylfuran, N,N-dimethylaniline, N-methylaniline, thiophenol, and benzyl mercaptan, were all able to act as nucleophiles to react with alkylglyoxal and 1,3-dicarbonyl compounds. The mechanim of this reaction was also investigated. The obtained 1,4-diketones can be easily converted to many valuable chemicals.
