Palladium-Catalyzed Silacyclization of (Hetero)Arenes with a Tetrasilane Reagent through Twofold C-H Activation

The use of an operationally convenient and stable silicon reagent (octamethyl-1,4-dioxacyclohexasilane, ODCS) for the selective silacyclization of (hetero)arenes via twofold C-H activation is reported. This method is compatible with N-containing heteroarenes such as indoles and carbazoles of varying complexity. The ODCS reagent can also be utilized for silacyclization of other types of substrates, including tertiary phosphines and aryl halides. A series of mechanistic experiments and density functional theory (DFT) calculations were used to investigate the preferred pathway for this twofold C-H activation process.

A new and efficient method for the synthesis of 3-(2-nitrophenyl)pyruvic acid derivatives and indoles based on the Reissert reaction

The formation of 3-(2-nitrophenyl)pyruvic acid and its amide and ester derivatives – key compounds for the Reissert indole synthesis – was achieved under various reaction conditions via the acid catalyzed hydrolysis of 5-(2-nitrobenzyliden)-2,2-dimethyl-1,3-oxazolidin-4-one, which is readily available from 3-(2-nitrophenyl)oxirane-2-carboxamide. A new and highly efficient method for the synthesis of indole-2-carboxylic acid derivatives via the intramolecular reductive cyclization of o-nitrophenylpyruvic acid and its amide and ester derivatives was developed using Na2S2O4 in dioxane/water at reflux.

Pd-Catalyzed Ortho-Directed C-H Glycosylation of Arenes Using N-linked Bidentate Auxiliaries

Main observation and conclusion A set of Pd-catalyzed ortho-directed C-H glycosylation reactions with glycosyl chloride donors using various N-linked bidentate auxiliaries has been developed for synthesis of C-aryl glycosides. A broad range of pyranose and furanose moieties can be installed on the ortho position of arylamine, carbazole, indole and benzylamine type substrates in high yield and with high regio- and diastereoselectivity. These auxiliaries can be readily installed and removed under relatively mild conditions.

Identification and functional study of an iif2 gene cluster for indole degradation in Burkholderia sp. IDO3

Burkholderia sp. IDO3 is an indole-degrading bacterium isolated from activated sludge. A previous genomic clone library assay identified an iif1 gene cluster for indole metabolism in strain ID03. To further explore the underlying indole degradation mechanisms, the complete genome of strain IDO3 was sequenced (8,003,806 bp). The genome contained three circular chromosomes and one plasmid, and 7550 genes were predicted. Interestingly, in addition to iif1 on chromosome 3, bioinformatic analyses identified a second indole oxygenase gene cluster, iif2, on chromosome 1. Both iif clusters were up-regulated in response to indole. Heterologous expression of iifC1D1 and iifC2D2 in Escherichia coli BL21(DE3) demonstrated that these genes were capable of oxidizing indole to indigo. Gene knockout assays provided additional evidence that iifC2 played crucial roles in indole metabolism. In addition, we identified a novel gene (iifF) in the iif2 cluster. This gene was shown to encode an isatin hydrolase. IifF was expressed in E. coli, and a purified his-tagged enzyme preparation was obtained. IifF converted isatin to isatinate with K-m of 4.4 +/- 0.7 mu M and k(cat) of 95.5 +/- 4 s(-1). This is the first study to show that indole can be degraded by two iif gene clusters, and that isatin hydrolase is involved in indole metabolism, improving our understanding of indole metabolic processes.
