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 synthesised in a four component one-pot reaction combining an enantioselective organocatalytic Michael addition with the diastereoselective nitro- Mannich/lactamisation cascade. Protodenitration and chemoselective reductive manipulation of the heterocycles was used to install contiguous and fully substituted stereocentres in the synthesis of substituted piperidines.

, p. 471 - 473 (2016)
Pharmacology-relevant compounds bearing structural fragments of racetam nootropics, wound-healing acyclic isoprenoids and neurotropic GABA analogues, were enantioselectively (up to 94% ee) synthesized from available and inexpensive precursors.

Pentacoordinated spirophosphorane as a simple, effective and novel organocatalyst for the Michael addition reaction has been investigated. The bisaminoacyl spirophosphorane that possessed a thiourea-like moiety and an amine group was applied to the Michae

We have prepared [2]rotaxanes, the behavior of which as switchable catalysts depends on their pirouetting motion, which can be controlled through the addition and removal of Na+ ions. At least three sequential on/off cycles of a Michael reactio
A thiourea-functionalized metal-organic macrocycle for the catalysis of Michael additions and prominent size-selective effect

A discrete tetranuclear thiourea-based metal-organic macrocycle (MOM) with a large size was constructed by a well-designed organic ligand and nickel(ii) ions via self-assembly. Incorporating thiourea groups as hydrogen-bond donors into a metal-organic com
