- Ligand-Enabled Gold-Catalyzed C(sp2)-N Cross-Coupling Reactions of Aryl Iodides with Amines
-
The first example of ancillary (P,N)-ligand-enabled gold-catalyzed C-N cross-coupling reactions of aryl iodides with amines is reported. The high generality of the reaction in de novo synthesis, late-stage modifications, and cascade processes to access functionalized indolinones and carbazoles underscores the synthetic potential of the presented strategy. Monitoring the reaction with ESI-HRMS and NMR provided strong evidence for the in situ formation of putative high valent Au(III) intermediates.

- Design, synthesis and antitumor activity of novel cis-furoquinoline derivatives
-
A series of novel cis-furoquinoline derivatives was synthesized and tested for their antitumor activities in vitro against HepG2 cells, Lu-04 cells and Leu02 cells to evaluate structure-activity relationships. Assay-based antiproliferative activity study revealed that several compounds had significant effects on cytotoxicity, among which compounds 2f, 2l, 2q were found to be the most active compounds. Above all, compounds 2f, 2l, 2q would be potential anticancer agents which deserved further research.
