A novel cross dehydrogenative coupling (CDC) reaction of N,N-dimethylanilines with methyl ketones by cooperative copper and aminocatalysis has been developed, which leads to the formation β-arylamino in 42-73% yields. Moreover, copper-catalyzed alkylation free (NH) indoles via CDC is also presented, affording alkylated 52-78%
Abstract Rapid and accurate identification of species is required for the biological control pest N octuoidea moths. DNA barcodes thin‐film biosensor chips are two molecular approaches that have gained wide attention. Here, we compare these methods a limited number moth species. Based on commonly used mitochondrial gene cytochrome c oxidase I (the standard barcode animal species), 14 probes were designed synthesized shared by national nature reserves in B eijing H ebei, C hina. Probes ranged...
Water-soluble small organic photothermal agents (PTAs) over NIR-II biowindow (1000-1350 nm) are highly desirable, but the rarity greatly limits their applications. Based on a water-soluble double-cavity cyclophane GBox-44+ , we report class of host-guest charge transfer (CT) complexes as structurally uniform PTAs for therapy. As result its high electron-deficiency, can bind different electron-rich planar guests with 1 : 2 host/guest stoichiometry to readily tune CT absorption band that...
One-pot mechanochemical synthesis was demonstrated to be an efficient strategy synthesize host–guest POM⊂rho-ZIF complexes (POM = polyoxometalate; rho-ZIF zeolitic imidazolate framework with rho topology) high crystallinity. In this work, the metastable large interior cavities and windows used as host matrix for encapsulating immobilizing bulky guest molecules loading efficiency chemical stability. As novel catalysts, were found effective selective oxidation of a series sulfides sulfoxides....
A dramatic concentration effect on the stereoselectivity of N-glycosylation, which is attributable to a low-concentration-facilitated remote-participation, has been disclosed, leading convenient synthesis 2′-deoxy-β-ribonucleosides biological significance.
Abstract Perylene diimides (PDIs), a well‐studied class of organic dyes, have strong tendency to self‐aggregate in water, thus greatly restricting their phototheranostic applications. Herein, we report water‐soluble PDI cyclophane “Gemini Box” ( GBox‐1 4+ ), consisting central chromophore enclosed by double‐sided cationic molecular straps. Owing the effective spatial isolation, self‐aggregation can be completely eliminated, even concentrated aqueous solution up 2 mM. To our knowledge,...
Two Co(II) metal-organic frameworks (Co-MOFs), namely, [Co(DMTDC)(bimb)]
Organic selenium compounds are important molecules with a wide range of applications in pharmaceuticals, organic materials, catalysis, and other fields. Herein, we report the synthesis α-selenomethylketones through reaction vinyl azides arylselenols benzylselenol. This protocol has advantages releasing only nitrogen as benign byproduct, using air an environmentally friendly initiator, very short duration, mild conditions, broad substrate compatibility. The results exploratory studies show...

As the first example of application chiral selenonium ylides in asymmetric cyclopropanation, a new strategy for highly stereoselective synthesis 1,2,3-trisubstituted cyclopropanes via is described. The reaction afforded three stereoisomers with good yields, excellent diastereoselectivities, very high enantioselectivities (up to >99% ee), generality and recyclability selenides. possible pathways models cyclopropanation were also proposed rationalize diastereoselectivities.
Tandem mass spectrometry (MS/MS) acts as a key technique for peptide identification. The MS/MS-based identification approaches can be categorized into two families, namely, de novo and database search. Both of the types benefit from an accurate prediction theoretical spectrum. A spectrum consists m/z intensity possibly occurring ions, which are estimated via simulating generating process. Extensive researches have been conducted prediction; however, methods suffer low prediciton accuracy due...
A <italic>syn</italic>-atropisomer precursor was employed to construct trapezoid-shape macrocycles, which can selectively recognize tryptophan from 20 standard amino acids.
A class of water-soluble macrocycles with gradually extended cavities were synthesized to selectively bind size-matched guests. One the host–guest products exhibited excellent near-infrared photothermal activity.
