In contrast to the extensive but non-recyclable use of tetraalkoxydiboron(4) compounds as stoichiometric reagents in diverse reactions, this article reports an atom-economical reaction using a commercial diboron(4) catalyst. The key success was designing catalytic cycle for radical [3 + 2] cycloaddition involving pyridine cocatalyst generate from catalyst and reversibly mediate transfer boronyl radicals. comparison with known transition metal-based catalysts, current features not only...
Based upon a radical polar effect, an intermolecular azidoheteroarylation of simple alkenes via metal-free multicomponent cascade process was achieved. It allows mild, rapid, and step-economic access to broad range azidoalkylated heteroaromatics. Given the diversity in transformations organic azides medicinally privileged scaffolds heteroarenes, this strategy enables efficient synthesis late-stage derivatization drugs candidates.
The southern Great Xing'an Range is one of the most important metallogenic belts in northern China, and contains numerous Pb–Zn–Ag–Cu–Sn–Fe–Mo deposits. Huanggang iron–tin polymetallic skarn deposit located Sn-polymetallic sub-belt. Skarns iron orebodies occur as lenses along contact between granite plutons Lower Permian Huanggangliang Formation marble or Dashizhai andesite. Field evidence petrographic observations indicate that three stages hydrothermal activity, i.e., skarn, oxide sulfide...
Abstract The degradation of world‐wide estuarine ecosystems as a result accelerated human population growth accompanied by agricultural, industrial and urban development justifies strong need to find efficient ways manage protect these sensitive environments. Starting from 2001, the authors have been involved in an interdisciplinary research project aiming develop environmental indicators for integrated ecosystem assessment Gulf Mexico. As part this project, study was conducted characterize...
Based on 88 well-dated and high-resolution paleoclimate records, global hemispheric stacks of the last deglacial climate were synthesized by utilizing normalized average method. A sequential relationship between West Antarctic Ice Sheet Divide ice core CO2 concentration composited proxy-based global–hemispheric was detected using Wilcoxon rank-sum test wavelet analysis. The results indicate that stack Northern Hemisphere started to increase slowly before 22 kabp, possibly due enhancement...
5-(Trimethylstannyl)-2H-pyran-2-one (11) and 3-(trimethylstannyl)-2H-pyran-2-one (30), readily prepared from the corresponding bromo-2H-pyran-2-ones, undergo Pd(0)-catalyzed coupling reactions with a variety of enol triflates to give 5- 3- substituted 2H-pyran-2-ones, respectively. This reaction is applicable 14beta-hydroxy-17-ketosteroids, therefore may prove useful in convergent syntheses lucibufagins bufadienolides.
The published global ocean tide models show good agreement in deep oceans and exhibit differences complex coastal areas, along with subsequent Ocean Tide Loading Displacement (OTLD) modeling differences. Meanwhile, OTLD parameters (amplitudes phase lags) derived by Global Positioning System (GPS) Precise Point (PPP) approach need long time to converge a stable state poor precision of S2, K1, K2 constituents. Based on the fact that no constraint is imposed current kinematic solution, new...
Owing to the lack of terrestrial heat flow data, studying lithospheric thermal structure and geodynamics Yingen‐Ejinaqi Basin in Inner Mongolia is limited.
