The Michael type addition of pyrroles and indoles bearing strongly electron-withdrawing N-protecting groups (e.g., arylsulfonyl-, benzoyl-) to methyl vinyl ketone have not been previously reported. We find that such alkylative processes can be effected in low to moderate yields using bismuth triflate as catalyst in conjunction with microwave irradiation. [GRAPHICS] .

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 96-69-5 is helpful to your research. Category: indole-building-block.

Indole based heterocyclic molecules are important and valuable structural unit that are present in various biologically active natural products, pharmaceuticals and agrochemicals. In this paper, zinc oxide nanoparticles were explored as catalyst for the synthesis of 3-substituted indoles in water via ultra-sonication. The stability of ZnO nanoparticles and their dispersion in water was enhanced by grafting it with a biodegradable polymer (poly lactic acid). The proposed methodology is capable of providing desired products in good yield (83-97%) and 25 derivatives of indoles were synthesized. The green reaction metrics such as E-factor (0.16) and atom economy (97%) show that the present protocol is sustainable and economical. Also, the reactions were carried out in water under environmentally benign conditions that avoids use of any additives or hazardous solvents.

An indole-rich tripodal microtubule inhibitor is designed, which binds at the DCVJ site of tubulin and inhibits its polymerization. It causes apoptotic death of cancer cells without affecting normal cells and inhibits the growth of tumors. Finally, STD-NMR and TR-NOESY experiments reveal that the indole appendages play a crucial role in interacting with tubulin.

Eighteen dihydroindolizino[8,7b]indole derivatives 4a-r were designed, synthesized and evaluated as new alpha-glucosidase inhibitors. These derivatives were synthesized by an efficient one-pot two-step reaction under mild condition. All the synthesized compounds were found to be more active than the standard drug acarbose (IC50 = 750.0 +/- 1.5 mu M) with IC50 values in the range of 107.2 +/- 1.0-275.4 +/- 1.5 mu M. Among the synthesized compounds, diethyl derivative 4o and dimethyl derivative 4 h exhibited the highest anti-alpha-glucosidase activities (IC50 = 107.2 +/- 1.0 and 118.0 +/- 0.7 mu M, respectively). Kinetic analysis of the compound 4o revealed that this compound is a competitive inhibitor for alpha-glucosidase with Ki value of 113 mu M. Furthermore, the docking study on the compounds 4o and 4 h revealed that these compounds interacted with the important residues in the active site of the homology model of alpha-glucosidase.

An effective and operationally simple method for the preparation of 1-(2-(sulfonamido)vinyl)indoles (SAV-indoles) by the Rh(II)-catalyzed reaction of 2,2-diaryl-2H-azirines with 1-sulfony1-1,2,3-triazoles has been developed. This method enables the stereoselective synthesis of a variety of 1,2,3-trisubstituted indoles having a Z configuration of the (1-aryl-2-(sulfonamido)vinyl) substituent. The reaction mechanism, supported by DFT calculations, involves the formation of 1,4-diazahexa-1,3,5-trienes, which rapidly cyclize to 2,2diaryl-1-sulfonyl-1,2-dihydropyrazines. These compounds can be isolated at an early stage of the reaction, but under prolonged heating they isomerize into 7aH-indolium ylides, followed by a barrierless 1,5-prototropic shift to SAV-indoles. The developed methodology was also applied to the preparation of 1,3′-biindoles from 2,2-diaryl-2H-azirines using 3-diazoindolin-2-imines instead of 1-sulfonyl-1,2,3-triazoles.

Indole derivatives are important heterocycles in organic synthesis for serving as privileged building blocks for functional material and as key components in a lot of bioactive compounds. Propargylic alcohols, bearing alkynyl and hydroxyl functional groups, have emerged as promising feedstock materials for the construction of carbo- and heterocycles. Especially, in the last decade, the Lewis or Bronsted acid catalysed tandem annulations of propargylic alcohols to build structurally diverse indole derivatives have been well-investigated. In this review, we summarize two main synthetic strategies toward indole derivatives via the cascade reactions of propargylic alcohols: indole-ring formation involved tandem reactions and the direct function-alization of indole skeletons. We hope this review would help to develop new and more efficient protocols for the synthesis of indole-included N-heterocycles.
