Solvent effects: vibrational circular dichroism (VCD) revealed pronounced solvent‐induced conformational shifts for a tetradentate salen ligand in CDCl3, a solvent generally considered benign. Contrary to the DFT prediction of a single dominant conformer family, quantum cluster growth together with the genetic algorithm guided VCD analysis uncovered ...

Diastereoselective Total Synthesis of Salvileucalin C
A concise and efficient approach for the diastereoselective total synthesis of salvileucalin C, as well as their biosynthetically related diterpenoids salvileucalin D, salvipuberulin, isosalvipuberulin, and dugesin B, has been reported for the first time.

Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Total Asymmetric Synthesis of Glycomimetics and Polypropionates of Biological Interest
Using readily available chiral auxiliaries such as (+)- and (?)-camphanic acid, (R,R)- and (S,S)-tartaric acid derivatives (e.g. RADO(R)-COCl, SADO(R)-COCl) efficient diastereoselective syntheses of rare sugars and glycomimetics have been ...

Cationic Permethylated Cyclodextrins Capable of Self‐Assembling Into Linear Nanostructures in Water
A quaternary ammonium bridge equipped with a lipophilic substituent in permethylated cyclodextrins suppresses undesired supramolecular interactions and promotes controlled, directional head‐to‐tail self‐assembly into well‐defined linear nanostructures.

Diastereoselective Synthesis of (±)-epi-Subincanadine C
Starting from indolylmaleimide, concise and efficient total synthesis of (±)-epi-subincanadine C was described via stereoselective Wittig olefination, base-induced selective mono-prenylation, regioselective Grignard reaction, diastereoselective Pictet ...

Towards the total synthesis of keramaphidin B
The enantio- and diastereoselective Michael addition of a δ-valerolactone-derived pronucleophile to a substituted furanyl nitroolefin catalysed by a bifunctional cinchonine-derived thiourea has been used as the key stereocontrolling step in a new ...
