An environmentally-friendly and facile protocol for the construction of tetrasubstituted alkenes has been established with Ru(ii)-catalyzed C-H bond functionalizations under mild conditions. The method features the usage of readily available substrates, without external oxidants and additives, 100% atom economy, and excellent regioselectivity, thus enhancing the practicability of this protocol. Moreover, this transformation proceeded smoothly under aqueous conditions and could be extended to the gram scale. N-Methoxyamide, as a directing group (DG), played a vital role in the transformation.

A group of new acetylenic derivatives of indole was synthesized by condensation of 2- and 3-iodoindoles with terminal acetylenes. 3-Iodoindole unsubstituted at the heteroatom is distinguished by an increased tendency to undergo deiodination under the reaction conditions.Chemical transformations of the synthesized acetylenic derivatives were carried out, proceeding with both the retention of and with the participation of the triple bond.In the intramolecular cyclization of vicinal, functionally substituted indolylacetylenes, a tendency is manifested to form six-membered heterocycles.A primary pharmacological investigation of the compounds obtained was carried out.Most of them are slightly toxic, several of the compounds display in high doses indications of neurotropic activity.

The most promising compound 27 showed strong anti-tumor activity against A549, H460, HT-29 and SMMC-7721 cell lines with IC50 values of 22, 0.23, 0.65 and 0.77 nM, which were 2.6-, 83-, 1.1 × 103- and 2.0 × 103- fold more active than MX-58151 (IC50 values of 0.058, 0.019, 0.70 and 1.53 muM), respectively.

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.Application of 399-76-8, you can also check out more blogs about399-76-8

A bipolar host material for green phosphorescent organic light-emitting diodes (OLEDs) was designed and synthesized through a combination of dibenzothiophene, alpha-carboline, and carbazole (DTCC) moieties. The synthesized host material showed a sufficient HOMO/LUMO bandgap (3.49 eV) and triplet energy (2.67 eV) for green emitting bis[2-(2-pyridinyl-N)phenyl-C] (acetylacetonato) iridium(III) [Ir(ppy)2(acac)]. From the results of a single charge device for DTCC, the hole current density of DTCC was similar to the electron current density, indicating that DTCC possesses bipolar charge transport properties, confirming its bipolar nature and thus its applicability as the host of PHOLED. Thus, the DTCC host showed efficient energy transfer to the Ir(ppy)2(acac) dopant in the device. A maximum external quantum efficiency of 18.9% was obtained using DTCC as the host material and the color coordinate of the green PHOLED was (CIEx,y = 0.34, 0.62) at 10% doping concentration.

A direct and highly stereoselective approach for the synthesis of Z-alkenyl-pyranoindoles had been developed by utilizing Rh(II)-catalyzed intramolecular cyclization of N-sulfonyl-1,2,3-triazoles with indole derivatives. A variety of pyranoindoles were obtained in 44-93% yields. Moreover, a more convenient synthesis of pyranoindoles starting from terminal alkyne was realized via a Cu-Rh sequentially catalyzed one-pot cascade reaction.
