Light-driven dynamic pattern formation.

Anhydro sugars, valuable intermediates in carbohydrate syntheses

The versility of the epoxyhydroxy functionlity in pyranoses is demonstrated giving access to sugar amino acids and peptides, aminodeoxy, halodeoxy , branched-chain, cyclopropanated and aziridino sugars.

Building Bridges: Biocatalytic C–C-Bond Formation toward Multifunctional Products

Carbon-carbon bond formation is the key reaction for organic synthesis to construct the carbon framework of organic molecules. The review gives a selection of biocatalytic C-C-bond-forming reactions which have been investigated during the last 5 years and which have already been proven to be applicable for organic synthesis. In most cases, the reactions lead to products functionalized at the si...

An efficient and general route to reduced polypropionates via Zr-catalyzed asymmetric CC bond formation.

An efficient and general method for the synthesis of reduced polypropionates has been developed through the application of asymmetric carboalumination of alkenes catalyzed by dichlorobis(1-neomenthylindenyl)zirconium [(NMI)(2)ZrCl(2)]. In this investigation, attention has been focused on those reduced polypropionates that are alpha-monoheterofunctional and either omega-ethyl or omega-n-propyl. ...

N-Heterocyclic carbene containing element organic frameworks as heterogeneous organocatalysts.

A bifunctional imidazolium linker was used for the production of highly crosslinked element organic frameworks by Suzuki-coupling with tetrafunctional boronic acids. The resulting porous materials are good heterogeneous organocatalysts in the N-heterocyclic carbene-catalyzed conjugated umpolung of α,β-unsaturated cinnamaldehyde.
