As part of an investigation into new synthetic routes to poly(peri-naphthalene), the synthesis and cycloaromatization of tetraethynylbiphenyls is described. The...

The formation of ethers by C−O bond formation under harsh basic or acidic conditions is an entrenched synthetic disconnection in organic chemistry. We report a strategic...

We synthesized uniform pore-sized mesoporous silica spheres embedded with magnetite nanocrystal and quantum dots. The magnetic separation, luminescent detection, and controlled...

The regioselective carboindation of simple alkenes with indium tribromide and ketene silyl acetals was accomplished. Various alkenes such as ethylene, 1-alkenes, and cyclic...

Background The M2 phenotype of tumor-associated macrophages (TAM) inhibits the anti-tumor inflammation, increases angiogenesis and promotes tumor progression. The transcription...

Replacing the 17α-acetoxy substituent in an antiprogestational 17β-acetyl-11β-arylestra-4,9-dien-3-one by 3-hydroxypropyl significantly diminished glucocorticoid receptor...

Allylically oxygenated vinyl α-triphenylstannanes such as 22 can be readily converted into vinyl iodides and thereafter stereodefined trisubstituted alkenes with retention of...

A silver galvanic displacement process on commercial aluminum foil has been carried out to produce cost-effective SERS substrates. The process is based on an extremely simple...

International audience; The synthesis, characterization, and luminescent behavior of trivalent Sm, Eu, Dy, and Tb complexes of two enantiomeric, octadentate, chiral,...

Background Magnesium (Mg2+) is an essential cation implicated in carcinogenesis, solid tumor progression and metastatic potential. The Transient Receptor Potential Melastatin...

The reduction of benzo-1,2,3,4-tetrazine 1,3-dioxides (BTDOs) 1 with Na2S2O4 or SnCl2 is suggested to proceed via intermediate N-nitrosobenzotriazoles 3 to afford benzotriazoles...

We revealed the first example of a crystalline lithium aluminate nanotube with thermal stability prepared by a surfactant-driven hydrothermal procedure. The obtained nanotube...

Construction of Novel Polycyclic Ring Systems by Transition-Metal-Catalyzed Cycloisomerization of Ene−Ene−Ynes. Interception of a Carbenoid Intermediate in Skeletal...

An unidentified tunicate from Pohnpei, Micronesia, yielded sagittamides A and Bcompounds comprising a long-chain C26 dicarboxylic acid that acylates terminal l-valine and...

A highly step-economic asymmetric synthesis of the tetracyclic structure assigned to the medicinal alkaloid jamtine has been accomplished using a chiral lithium amide base...

Previous studies demonstrate that nitric oxide (NO) promotes p53 transcriptional activity by a classical DNA damage responsive mechanism involving activation of ATM/ATR and...

Several Precipiton phosphines were prepared and employed in the Staudinger reaction and in the reduction of secondary ozonides. Both amines and aldehdyes were obtained in good...

Self-assembly of various phthalocyanine (Pc) molecules and a derivative on an epitaxial graphene monolayer (MG) has been investigated by means of in situ ultrahigh vacuum...

A novel metal−organic framework (MOF), (NH4)2(adp)[Zn2(ox)3]·3H2O (1) was synthesized and its structure was determined. We propose three types of rational design to introduce...
