Author is Fu, Liangbing; Davies, Huw M. L..

An efficient synthesis of tetrahydrocarboline-type products and polycyclic spiroindolines was achieved. The transformation proceeds via rhodium(II)-catalyzed intramol. annulations of indolyl- and pyrrolyl-tethered N-sulfonyl-1,2,3-triazoles. The reaction could be tuned toward either the formal [3 + 2] cycloaddition or the C-H functionalization reaction depending on the electronic and structural features of the substrates, leading to the production of a variety of structurally related heterocyclic compounds

Application of 51856-79-2. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Methyl 2-(1-methyl-1H-pyrrol-2-yl)acetate, is researched, Molecular C8H11NO2, CAS is 51856-79-2, about Enantioselective intermolecular radical C-H Amination. Author is Jin, Li-Mei; Xu, Pan; Xie, Jingjing; Zhang, X. Peter.

Radical reactions hold a number of inherent advantages in organic synthesis that may potentially impact the planning and practice for construction of organic mols. However, the control of enantioselectivity in radical processes remains one of the longstanding challenges. While significant advances have recently been achieved in intramol. radical reactions, the governing of asym. induction in intermol. radical reactions still poses challenging issues. We herein report a catalytic approach that is highly effective for controlling enantioselectivity as well as reactivity of the intermol. radical C-H amination of carboxylic acid esters with organic azides via Co(II)-based metalloradical catalysis (MRC). The key to the success lies in the catalyst development to maximize noncovalent attractive interactions through fine-tuning of the remote substituents of the D2-sym. chiral amidoporphyrin ligand. This noncovalent interaction strategy presents a solution that may be generally applicable in controlling reactivity and enantioselectivity in intermol. radical reactions. The Co(II)-catalyzed intermol. C-H amination, which operates under mild conditions with the C-H substrate as the limiting reagent, exhibits a broad substrate scope with high chemoselectivity, providing effective access to valuable chiral amino acid derivatives with high enantioselectivities. Systematic mechanistic studies shed light into the working details of the underlying stepwise radical pathway for the Co(II)-based C-H amination.

Related Products of 51856-79-2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Methyl 2-(1-methyl-1H-pyrrol-2-yl)acetate, is researched, Molecular C8H11NO2, CAS is 51856-79-2, about Pretreatment of sweet sorghum stalk with aqueous hydrogen peroxide for enhancing methanolysis and property of the bio-oil.

Alcoholysis is a promising approach for converting biomass into fuels and/or chems. under mild conditions. However, the effect of pretreatment on biomass alcoholysis was rarely reported. Herein, the effect of pretreatment with H2O2 on sweet sorghum stalk (SSS) methanolysis was examined The results show that the pretreatment could markedly improve the bio-oil (BO) yield and decrease the appropriate temperature for obtaining maximum BO yield. The appropriate temperature for pretreated SSS methanolysis was determined to be 280 °C and the maximum BO yield is 44 wt%. In addition, higher heating values of the BOs were also enhanced based on elemental anal. According to anal. with gas chromatograph/mass spectrometer, phenolic compounds, esters, and sugars are predominant in the BOs, and the yield of phenolic compounds significantly increased from 91.75 to 111.68 mg·g-1 by the pretreatment. Moreover, polar species in the BOs decreased and deoxygenation occurred during pretreated SSS methanolysis. Analyses with scanning electron microscope and N2 physisorption reveal that pretreated SSS has more grooves and higher sp. surface area and anomalous porosity than SSS. According to analyses with Fourier transform IR spectrometer and X-ray photoelectron spectrometer, oxygen functional groups mainly in the forms of C=O and COO were introduced into SSS by the pretreatment. The changes of phys. and chem. structures should be responsible for enhancing SSS methanolysis and property of the BO.
