Enantioselective Synthesis of [6]Carbohelicenes.
Journal of the American Chemical Society, 2017The use of α-cationic phosphonites derived from TADDOL as ancillary ligands has allowed a highly regio- and enantioselective synthesis of substituted [6]carbohelicenes by sequential Au-catalyzed intramolecular hydroarylation of diynes.

A highly enantioselective synthesis of indolines by asymmetric hydrogenation of 1H-indoles and 3H-indoles at ambient temperature and pressure, catalyzed by chiral phosphine-free cationic ruthenium complexes, has been developed.

Pyrrolo[1,2-a]indoles are privileged structural elements of many natural products and pharmaceuticals. An efficient one-step process for their highly diastereo- and enantioselective synthesis, comprising a direct [3+2]-cycloaddition, has been developed ...

An enantioselective synthesis of (−)-alloyohimbane
Tetrahedron Letters, 1988AbstractThe key step in the synthesis of the alkaloid (VII) mentioned in the title is the photolytic rearrangement of the spiro‐fused oxaziridines (III) to give the decahydroisoquinolinones (IV) and (V).
