- 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.

- 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.
