with corresponding model catalysts featuring weakened cage architecture and functionality. A diquinoxaline‐spanned resorcin[4]arene bearing Lewis acid and base components selectively catalyzed alkynehydration, allowing us to investigate structure–activity relationships and to identify significant skeletons.

The present invention relates to chiral ligands deriving from α- and β-amino acids, and from metal complexes formed from the same. The ligands are useful with catalytic gold complexes, particularly Au(I) complexes.
Despite the widespread use of transition-metal catalysts in organic synthesis, transition-metal-catalyzed reactions of organosulfur compounds, which are known as catalyst poisons, have been difficult. In particular, the transition-metal-catalyzed addition of organosulfur compounds to unactivated alkenes remains a challenge. A novel gold-catalyzed hydrothiolation of unactivated alkenes is presented, which

In one embodiment, the application discloses ligands, such as a ligand from a dihydrobenzo [1,3] oxaphosphole scaffold, and palladium or other transition metal complexes comprising the ligands and methods for performing cross coupling reactions and asymmetric cross coupling reactions with high selectivity and efficiency, under aqueous micellar catalysis conditions.

Modular gold amide chemotherapeutics: Access to modern chemotherapeutics with robust and flexible synthetic routes that are amenable to extensive customisation is a key requirement in drug synthesis and discovery. A class of chiral gold amide complexes featuring amino acid derived ligands is reported herein. They all exhibit in vitro cytotoxicity against two slow growing breast cancer cell lines with limited toxicity towards normal epithelial cells.
