application of hydroformylation to the synthesis of quaternary carbon centers is reported. The synthesis of the highly substituted carbon is achieved by applying a catalyticamount of 1. Ligand 1 serves as a catalyticdirectinggroup by covalently and reversibly binding to both the substrate and catalyst. The intramolecular nature of the directinggroup strategy accelerates the hydroformylation reaction
A general and efficient method for the electroreductive carboxylation of arylepoxides with CO2 has been developed to provide β-hydroxy acids. The method exhibited broad substrate scope, could be extended to cyclic ethers with larger rings, and proved to be a powerful approach to the late-stage carboxylation of natural product derivatives and drug molecules.
