Carreras, Lucas published the artcileSelective functionalisation of aromatic alcohols with supramolecularly regulated gold(I) catalysts, Recommanded Product: 2,5,8,11-Tetraoxatridecan-13-ol, the main research area is hydroxyaryl carbonyl derivative preparation gold catalyst; aromatic alc diazo ester carbon hydrogen insertion reaction.

Phosphite-based Au(I) catalytic systems containing an array of structurally diverse polyether-based regulation sites were designed and synthesized. These catalysts have been successfully tested in the Au(I)-catalyzed C-H functionalization of phenols and related derivatives with gold-carbenes derived from diazo compounds Regulation of the steric congestion around the catalytic Au(I) center via ion-dipole interactions with an external regulation agent led to an enhancement of both the activity and selectivity of the reaction. This new approach in supramol. gold(I) catalysis has been applied to the derivatisation of an array of substituted phenols and related substrates and to the preparation of an advanced synthetic intermediate of the anticancer agent tamoxifen. The effects of the regulation agent on the selectivity and yield of the reaction have been studied and rationalised using DFT-D calculations

Wu, Yi published the artcileApplication of GC × GC coupled with TOF-MS for the trace analysis of chemical components and exploration the characteristic aroma profile of essential oils obtained from two tree peony species (Paeonia rockii and Paeonia ostii), SDS of cas: 23783-42-8, the main research area is Paeonia rockii ostii essential oil aroma GC TOF MS.

Tree peony essential oil (EO) is a critical material for flavor and function in the industrial fields of perfume, medicine and food. To conduct an overall anal. of different varieties of tree peony EOs, the composition, aroma characteristics and antioxidant activity of ZiBan and FengDan EOs were analyzed by two-dimensional gas chromatog. and time-of-flight mass spectrometry (GC × GC-TOF/MS) and the odor activity value (OAV). A total of 151 and 123 compounds were identified in ZiBan and FengDan EOs, resp., in which ZiBan EO was characterized by alc., alkane and acid, and FengDan EO was represented by aldehyde, alc. and terpene. Nevertheless, there were great differences in the content of coexisting substances in the two kinds of EOs. The aroma result indicated that the characteristic aroma and intensity of the two kinds of tree peony EOs were completely different; the aroma of ZiBan EO was mainly composed of fruity and floral aromas, whereas that of FengDan EO primarily consisted of fruity, fatty, grass and floral odors. The antioxidant activities of ZiBan EO was better than that of FengDan EO. The total antioxidant activities of ZiBan and FengDan EOs were found to be 0.020 mg Vc/mL EO and 0.003 mg Vc/mL EO, while the DPPH radical scavenging abilities of ZiBan and FengDan EOs were 24.77% and 21.60%, resp.

Klepel, Florian published the artcilePhoto-responsive host-guest complexation directs dynamic covalent condensation of phenyl boronic acid and D-fructose, Application In Synthesis of 23783-42-8, the main research area is photoresponsive host guest complexation directs dynamic covalent condensation; dynamic combinatorial libraries mol recognition; dynamic covalent system responds rapidly conformation change.

Inspired by the way templates have been used to drive dynamic combinatorial libraries by mol. recognition, we exploited the photo-responsive host-guest interaction of an azo-based photoswitch with permethylated cyclodextrin to reversibly manipulate the dynamic covalent interaction of a Ph boronic acid and D-fructose by irradiation with light.
