Enantioselective organocatalysis of Strecker and Mannich reactions based on carbohydrates
Efficient organocatalysts for enantioselective Strecker and Mannich reactions were constructed from glucosamine as a readily accessible chiral scaffold. A variety of aromatic aldimines were subjected to hydrocyanation with good to excellent yield (72-98%)

Copper-catalyzed multicomponent cascade process for the synthesis of hexahydro-1H-isoindolones
(Chemical Equation Presented) Copper-catalyzed coupling of imines, dienylstannanes, and acryloyl chlorides followed by a Diels-Alder reaction afforded hexahydro-1H-isoindolones. Diversification of the core via Pd-catalyzed cross-coupling defines a new modular approach to isoindolone combinatorial libraries.
