Among the twenty natural proteinogenic amino acids, proline is unique as its secondary amine forms a tertiary amide when incorporated into biopolymers, thus preventing hydrogen bond formation. Despite the lack of hydrogen bonds and thanks to conforma

An efficient atom-economic rhodium-catalyzed asymmetric arylative cyclization to access enantioenriched 1-tetralones, bearing a quaternary carbon stereocenter, is described, involving a highly regioselective alkyne insertion, a 1,4-Rh shift, and an a

The formation of chiral 5- and 7-membered tetrahydrofurans and tetrahydrobenzo[ d]oxepines is achieved via arylative cyclization of simple O-tethered alkyne-enoates in the presence of arylboronic acids and chiral dienes-rhodium catalyst under mild co

In contrast to the intermolecular rhodium-catalyzed asymmetric 1,4-addition of organometallic reagents to activated alkenes, the asymmetric arylative cyclization of a diastereoisomeric E/Z mixture of 1,6-enynes afforded only one major enantiomer.
