An efficient and practical entry to 2-amido-dienes and 3-amido-trienes from allenamides through stereoselective 1,3-hydrogen shifts

Beilstein Journal of Organic Chemistry, 2011
Preparations of de novo acyclic 2-amido-dienes and 3-amido-trienes through 1,3-hydrogen shifts from allenamides are described. These 1,3-hydrogen shifts could be achieved thermally or they could be promoted by the use of Brønsted acids.

Combinatiorial method for surface-confined sensor desing and fabrication [PDF]

, 2005
The procedure for the combinatorial fabrication of new sensing materials for cations and anions based on self-assembled monolayers (SAM) is discussed. A library of different sensitive substrates is generated by sequential deposition of fluorophores and ...

Bis[μ-N-(tert-butyldimethylsilyl)quinolin-8-aminato-1:2κ2N1,N8:N8](N,N,N′,N′-tetramethylethane-1,2-diamine-1κ2N,N′)lithiumsodium

Acta Crystallographica Section E, 2012
In the heterometallic title bulky amido complex, [LiNa(C15H21N2Si)2(C6H16N2)], both alkali metal ions are four-coordinated with distorted tetrahedral geometries. The Li+ ion is N,N′-chelated by the N-silylated amido ligand, with Li—N =

Bimetallic Complexes Supported by a Redox-Active Ligand with Fused Pincer-Type Coordination Sites [PDF]

, 2015
The remarkable chemistry of mononuclear complexes featuring tridentate, meridionally chelating “pincer” ligands has stimulated the development of ligand frameworks containing multiple pincer sites. Here, the coordination chemistry of a novel pentadentate

Digestibilidade aparente de dietas contendo diferentes níveis de amido para coelhos em crescimento Apparent digestibility of diets with different starch levels for growing rabbits

Revista Brasileira de Zootecnia, 2000
Com o objetivo de avaliar a influência do amido dietético sobre a digestibilidade aparente dos nutrientes, para coelhos em fase de crescimento, quatro dietas experimentais foram elaboradas de forma a conter níveis crescentes de amido de milho (23, 28, 33

Nigrosine staining of wheat endosperm proteolipid patterns on starch gels [PDF]

, 1975
We have previously characterized a group of proteolipids from wheat endosperm, designated CM proteins, which are soluble in chloroformmethanol (2:1, v/v) and have a molecular weight lower than 25,000 daltons (1-3).

Relative Reactivity of the Metal-Amido versus Metal-Imido Bond in Linked Cp-Amido and Half-Sandwich Complexes of Vanadium [PDF]

, 2008
Treatment of (η5-C5H4C2H4NR)V(N-t-Bu)Me (R = Me, i-Pr) and CpV(N-p-Tol)(N-i-Pr2)Me (Cp = η5-C5H5) with B(C6F5)3 or [Ph3C][B(C6F5)4] results in formation of the corresponding cations, [(η5-C5H4C2H4NR)V(N-t-Bu)]+ and [CpV(N-p-Tol)(N-i-Pr2)]+.

Covalent Bonds Reinforced Strength and Modulus of Heterocyclic Aramid Fiber by Interfacial Aminated‐MXene Nanosheets

Advanced Science, EarlyView.
We demonstrate the covalent bonds strategy to enhance the mechanical property of PBIA fiber by using interfacial MXene‐NH2 nanosheets. The MXene‐NH2 nanosheets with reactive amino sites that can serve as nucleating agents and chain anchors to enhance orientation, crystallinity and interchain interaction of PBIA fiber via strong interfacial amido ...

Intestinal Source Control of Lipid Metabolism by Enzyme‐Probiotic Encapsulated, Spatiotemporal Crosslinked, and Small Intestine‐Adhesive Hydrogel Microspheres

Advanced Science, EarlyView.
A thiol‐modified alginate hydrogel microsphere‐encapsulated enzyme‐probiotic biohybrid (AKK‐COD) system has been developed to address the spatiotemporal delivery and colonization challenges of small intestine‐targeted probiotic for lipid metabolism regulation. The system exerts sequential functions of intragastric protection, small intestinal adhesion,
