Switchable organocatalysis from N-heterocyclic carbene-carbodiimide adducts with tunable release temperature [PDF]
N-Heterocyclic carbenes (NHCs) are powerful organocatalysts, but practical applications often require in situ generation from stable precursors that “mask” the NHC reactivity via reversible binding.

Whole Cells as Biocatalysts in Organic Transformations
Currently, the power and usefulness of biocatalysis in organic synthesis is undeniable, mainly due to the very high enantiomeric excess reached using enzymes, in an attempt to emulate natural processes.

Asymmetric organocatalysis involving double activation
Asymmetric organocatalysis contributed tremendously to the field of organic synthesis since year 2000. Considering the diversity of organocatalysts and their activation modes, chemists developed the double activation strategy, in which two distinct ...
