The chiral source and its mechanism in the molecular system are of great significance many fields. In this work, we proposed visualized methods to investigate physical a molecule, where electric magnetic interactions with transitional dipole moment, quadrupole their tensor product. This will also serve as an effective means visualizing interaction light matter. relationship between Raman optical activity (ROA) response structure was analyzed intuitive way. chromophore chirality vibration...
Abstract The Eburnamine‐Vincamine alkaloids have been studied intensively over the past six decades for their outstandingly potent vasorelaxation activity. Stereocontrolled assembly of C20/C21 adjacent chiral centers has a formidable challenge in synthesis this family. Herein, we report concise stereoselective total two trans ‐ring‐fused non‐natural analogues, (−)‐20‐ epi ‐Vincamine and ‐Eburnamonine, that features following key steps: a) continuous‐flow oxidation/lactam alcoholysis cascade...
Abstract In this work, the relationship between multiple solvent parameters and charge transfer index was analyzed by multi-factor multi-variate partial least squares regression (PLSR). The of molecule is visualized analysis excited state wave function. Hydrogen bond basicity surface tension can significantly affect studying solvation model index. Finally, a method in which regulates strength migration length proposed.
Infrared polarization detection has attracted wide applications in military and civilian fields by demonstrating more accurate target identification capabilities due to dimensional information. A multifocal metalens for simultaneous of the state incident light at dual wavelengths is proposed based on independent control orthogonally polarized light. When different wavelengths, array splits focuses three bases form six focal points with various positions. varying states be detected passes...
A concise stereoselective total synthesis of (±)-vindeburnol and its epimer (±)-16-epi-vindeburnol is presented. This synthetic work features the utilization Baeyer-Villiger oxidation to install different types lactone substrate, a sequence aminolysis, aldimine condensation acyl-Pictet-Spengler deliver crucial trans-fused indoloquinolizidine scaffold with high-level diastereocontrol.
Many novel physical properties of twisted bilayer graphene have been discovered and studied successively, but the mechanism chiral modulation BLG by a angle lacks theoretical research. In this work, density functional theory, wavefunction analysis excited state, quantum theory atoms in molecules are used to calculate analyze anti-symmetric characteristics zigzag-edge dots based on periodic complementary angles. The partial states shows that Moiré superlattices can effectively adjust...
This paper describes a concise, asymmetric and stereodivergent total synthesis of tacaman alkaloids. A key step in this is the biocatalytic Baeyer-Villiger oxidation cyclohexanone, which was developed to produce seven-membered lactones establish required stereochemistry at C14 position (92 % yield, 99 ee, 500 mg scale). Cis- trans-tetracyclic indoloquinolizidine scaffolds were rapidly synthesized through an acid-triggered, tunable acyl-Pictet-Spengler type cyclization cascade, serving as...

The aim of this research is to establish a new kind simple and rapid method determine amino acids metal elements in Citrus reticulata Blanco cv. Ougan fruit. high-performance liquid chromatography pre-column derivation was used test the contents found results showed that there were 17 kinds fruits two different mature periods. They could be separated easily within 30 min. correlation coefficients between peak area acid content above 0.99. sample-added recovery rate 96.0% 102.4%. Meanwhile,...
