The first enantioselective methodology for the synthesis of electron-poor 2-hydroxyalkyl- and 2-aminoalkyl furanes is demonstrated in this study. It utilizes a highly stereoselective organocatalytic one-pot reaction cascade: epoxidation or aziridinat

Aryl−iridium(III) hydride complexes with a P-coordinated phosphinate were formed from [Ir(cod)Cl]2 and secondary phosphine oxide−oxazoline ligands under basic conditions. The structure of these complexes, whose formation involved C−P cleavage,
