Microarc oxidation (MAO) is a common surface treatment technology for Mg alloys. The MAO layer, however, often fails to provide long-term protection due its inherent porosity. Current interests are mostly focused on strengthening the corrosion resistance by combining with other film techniques. In this work, we developed smart protective system characteristic of superhydrophobicity and active self-healing capability alloy integrating electro-assisted sol–gel deposition. porous precoating...
Nanocomposite reinforced polyurethane (PU) coatings have been prepared by an ultrasonication method with polydopamine-wrapped carbon nanotubes (PDA@CNTs) as the nanofiller. The influence of PDA@CNTs enhanced PU coating on corrosion resistance and adhesion strength to Al-alloy was investigated electrochemical impedance spectroscopy pull-off test during cyclic ageing tests, including salt spraying test, UV irradiation solution immersion. A comparison pristine against CNTs modified revealed...
Abstract Based on the discovery of copper‐catalyzed cyclopropanol ring‐opening addition to iminium ions, an unprecedented catalytic aerobic C−H oxidation/cyclopropanol cyclization cascade using CuCl 2 as multifunctional catalyst and air oxidant was developed construct azabicyclo[3.3.1]nonane skeleton, which is widespread in natural products medicines. Using this method, concise asymmetric total synthesis indole alkaloid (−)‐suaveoline achieved. This study not only provides efficient,...
Abstract Six multicomponent reactions were developed by using aldo‐X reagents and α‐oxoketene dithioacetals with indoles or amines as substrates, which can be used to prepare many heterocycles, such dihydrocoumarins, quinolines, furans pyrroles, in a straightforward way. A combination of two bifunctional is the key make discovery these possible because have minimum reactive sites, enable different substrates assembled together various manners.
We report here a homo-Mannich reaction of cyclopropanol with an iminium ion, generated by asymmetric allylic dearomatization indole, to construct tricyclic hydrocarbazole core, which is shared variety monoterpenoid indole alkaloids across families. Through this approach, all-carbon quaternary stereogenic center as well allyl and ketone group were installed. Using functionalized the structural platform, D ring E rings different sizes (i.e., five-, six-, seven-membered) successively or...
Abstract Tin (Sn)‐based perovskites have made notable advances with external quantum efficiency of over 20%, but still exhibit low electroluminescence brightness insufficient for outdoor displays. Here, it is demonstrated that compact phenethylammonium tin iodide (PEA 2 SnI 4 ) films an intact crystal structure can offer high luminance by optimizing the perovskite crystallization rate simultaneously engineering grain surface. Ammonium thiocyanate added to precursor solution generate film PEA...
ConspectusThe Mannich reaction, involving the nucleophilic addition of an enol(ate) intermediate to imine or iminium ion, is one most widely used synthetic methods for synthesis β-amino carbonyl compounds. Nevertheless, homo-Mannich which utilizes a homoenolate as partner and provides straightforward access valuable γ-amino compounds, remains underexplored. This can be largely attributed difficulties in generation manipulation species, despite various equivalents that have been developed....
A concise method to synthesize 1,2,3,4-tetrahydropyridines is described that involves the use of 2-alkoxy-3,4-dihydropyran as a modular precursor react with aniline and nucleophile. In this method, heteroatom dihydropyran ring was replaced by nitrogen while nucleophile attached its adjacent position. Various druglike polyheterocycles were prepared using NH2-containing 1,5- or 1,4-bisnucleophiles.
A Fe(NO3)3-mediated ring-opening arylation of cyclopropanol with the electron-rich pyrrole has been developed, which might proceed through oxidative radical ring opening followed by cyclization to motif and then aromatization. This method enables direct without prefunctionalization thus allows rapid access a diverse array chiral 5,6,7,8-tetrahydroindolizines from easily available amino acid esters. The synthetic utility demonstrated asymmetric synthesis alklaoids (-)-indolizidine 167B,...
Anemia is one of the most common diseases childhood and a health problem globally, particularly in developing counties children less than 2 years age. during has short- long-term effects on health. However, few studies have investigated prevalence anemia among Huaihua. Therefore, this study analyzed risk factors 6 to 23 months age This cross-sectional was conducted at maternal child care hospital Huaihua, from September November 2017. The population recruited using multistage sampling...
