Method for analysis of different oligosacchiride structures
In this study, an improved, rapid, high yield synthesis of N,N'-4,4'-bis(benzyl-2-boronic acid)-bipyridinium dibromide (o-BBV) is described. The obtained o-BVV is applied in a two-component saccharide sensing system (complex) where it serves as a fluoresc

Indole and quinoline derivatives and its preparation method and application
The invention provides an indoloquinoline derivative, a preparation method and application thereof in preparing antitumor drugs and antiviral drugs. The chemical structure of the indoloquinoline derivative is shown as a formula I. Experiments show that a partly-boric-acid-modified indoloquinoline derivative and a non-boric-acid-modified indoloquinoline derivative have strong inhibition effect on various tumor cell strains, thereby being capable of being used for preparation of the antitumor drugs, and have strong antiviral activity, thereby being capable of being used for preparation of the antiviral drugs.

Reductive coupling of polyfunctionalized organobismuth and organolead arylating reagents in the synthesis of benzopyran derivatives
Benzopyran derivatives were synthesized in good yields by the reactions of tris[2-(chloromethyl)phenyl]bismuth diacetate and 2-(halomethyl)aryllead triacetates with phenols and naturally occurring 4-hydroxycoumarins in the presence of bases according to a

Synthesis of (azidomethyl)phenylboronic acids
The synthesis of 2-, 3-, and 4-(azidomethyl)phenylboronic acids was carried out. The geometric and electronic structures were studied by quantum-chemical methods. The suggestion is made that there are weak intramolecular interactions between the boron atom and the nitrene nitrogen atom of the azido group.
Aryllead triacetates in the synthesis of oxaphenanthrene derivatives
Ortho-Halomethylphenyllead triacetates (halo = bromine or chlorine) react with phenols in the presence of triethylamine and a pyridine derivative to afford modest to good yields of dibenzo[b,d]-6H-pyrans.
