A versatile nitro-Mannich/lactamisation cascade for the direct stereoselective synthesis of heavily decorated 5-nitropiperidin-2-ones and related heterocycles has been developed. A highly enantioenriched substituted 5-nitropiperidin-2-one was synthes

A highly diastereoselective bifunctional organocatalyst controlled Michael addition, a nitro-Mannich/lactamization cascade, a furan N-acyliminium cyclisation, a sequential alkyne RCM/syn-reduction and an alkene RCM has allowed a 19 step, highly stere

The screening of a library of 9-amino(9-deoxy)epicinchonine derivatives (11 examples) presents thiourea CIN as the most reactive and enantioselective catalyst, although a number of the other catalysts are nearly suitable.

The marine alkaloid nakadomarin A (VII) is synthesized via a diastereoselective Michael addition reaction of ester (I) with nitro olefin (II) followed by a nitro-Mannich/lactamization of ester (III) as key steps.

A novel bifunctional organocatalytic Michael addition of a succinimide-derived pronucleophile to nitro olefins is described. The use of a range of nitro olefins afforded Michael adducts containing contiguous quaternary and tertiary stereogenic centre

A short and highly stereoselective synthesis of (-)-nakadomarin A has been developed using combinations of catalyst-controlled bond formations, one-pot multistep procedures, and powerful route-shortening reaction cascades. Several unprecedented chemi
