One-pot tandem reactions for direct conversion of thiols and disulfides to sulfonic esters, alcohols to bis(indolyl)methanes and synthesis of pyrroles catalyzed by N-chloro reagents

A convenient synthesis of sulfonic esters from thiols and disulfides has been described. In situ preparation of sulfonyl chlorides from thiols is accomplished by oxidation with Chloramin-T, tetra-butylammonium chloride (t-Bu4NCl) and water. The sulfonyl chlorides are then further allowed to react with phenol derivatives in the same reaction vessel. Also, a facile synthesis of bis(indolyl)methanes from alcohols using TCCA/KBr/wet-SiO2, and N-substituted pyrroles by reaction of hexane-2,5-dione with primary amines has been accomplished under mild condition with excellent yields.

Practical organic solvent-free Cu(OAc)2/DMAP/TEMPO-catalyzed aldehyde and imine formation from alcohols under air atmosphere

A highly efficient and practical organic solvent-free Cu(OAc)2/DMAP/TEMPO catalyst system for the selective aerobic oxidation of benzylic and allylic alcohols to aldehydes and phenones under an ambient air atmosphere was reported. A wide range of functional groups such as phenolic hydroxyl, amino, and methylthio are compatible with the catalyst system. The organic solvent-free aerobic oxidative imine synthesis from benzyl alcohol and amines was also achieved via the newly developed Cu(OAc)2/DMAP/TEMPO catalyst. 100 g-scale reactions for aldehyde and imine formation were achieved with over 90% yield using 0.5 mol% catalyst loading in 36 hours, presenting a potential valuable protocol for both economical and environmental considerations.

Enhanced adhesion and differentiation of human mesenchymal stem cell inside apatite-mineralized/poly(dopamine)-coated poly(?-caprolactone) scaffolds by stereolithography

The purpose of this study is to develop PCL scaffolds using stereolithography technology and induced modifications using a poly dopamine (PDA)-coated/HA precipitate to stimulate human mesenchymal stem cells (hMSCs). The chemical composition and surface properties of HA/PDA/PLA were characterized by XPS. HA/PDA/PLA modulated hMSCs responses in several ways. The extracellular matrix (collagen and fibronectin) adsorption was significantly higher on the substrates with the highest amount of PDA coating than on pure PCL. Increased focal adhesion kinase (FAK) levels and enhanced cell attachment were observed upon an increase in PDA content. The proliferation, alkaline phosphatase, osteogenesis-related proteins (OPN and BSP), and angiogenesis-related protein (vWF and ang-1) secretion of hMSCs were significantly stimulated when the PDA-coated concentration was increased. The PDA-coated/HA precipitate increases osteogenesis and angiogenesis of hMSCs cultured with a PCL scaffold. Our results demonstrate that this simple, bio-inspired surface modification of the organic PCL scaffold using PDA is a very promising tool for regulating cell behaviour, and may serve as an effective stem cell delivery carrier for bone tissue engineering.

Multiple Roles of the Pyrimidyl Group in the Rhodium-Catalyzed Regioselective Synthesis and Functionalization of Indole-3-carboxylic Acid Esters

A regioselective synthesis of indole-3-carboxylic acid esters from anilines and diazo compounds has been realized by making use of the pyrimidyl group-assisted rhodium-catalyzed C-H activation and C-N bond formation. The reaction proceeds under mild conditions, exhibits good functional group tolerance and scalability. Reutilization of the pyrimidyl directing group in the resulting products provided an efficient strategy for further C-7 functionalization of indoles. Moreover, the pyrimidyl moiety could be readily removed as a leaving group to offer various free N-H indoles.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 53855-47-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 53855-47-3, in my other articles.

Palladium-catalyzed C-H ethoxycarbonyldifluoromethylation of electron-rich heteroarenes

The first Pd-catalyzed C-H ethoxycarbonyldifluoromethylation with BrCF2CO2Et has been developed. The use of a bidentate phosphine ligand (Xantphos) is critical for the reaction to occur. A variety of electron-rich heteroarenes, including indoles, furans, thiophenes, and pyrroles, can be ethoxycarbonyldifluoromethylated in moderate to excellent yields. The reactions take place at the C-H bonds adjacent to the heteroatoms with high regioselectivity. This method provides a new protocol for the introduction of difuoroalkyl groups into electron-rich heteroarenes.

Intramolecular Construction of Trifluoromethyl Group by the Palladium-Catalyzed Alkylation of 2,3,3-Trifluoroallylic Carbonates with Indoles

The palladium-catalyzed alkylation reaction of 2,3,3-trifluoroallylic carbonates with indoles afforded a trifluoromethyl group possessing 3-substituted indole derivatives. The reaction proceeded via attack of the C-3 carbon of the indoles onto the C-2 position of the allylic moiety and intramolecular construction of the trifluoromethyl group by the intramolecular fluorine atom shift from the C-2 position to the C-3 position of the allyl unit.
