A combined experimental and theoretical study on realizing and using laser controlled torsion of molecules

, 2009
It is demonstrated that strong laser pulses can introduce torsional motion in the axially chiral molecule 3,5-diflouro-3',5'-dibromo-biphenyl (DFDBrBPh).

Stereospecific Assembly of Triply Chiral Pseudopeptidic Cages Through Dynamic Dual Chirality Transfer

Angewandte Chemie, EarlyView.
The spontaneous assembly of triply chiral (L, Δ, P or D, Λ, M) cages has been achieved from a simple tripodal chiral effector based on phenylalanine tris(amidoamine), non‐chiral bipyridine dialdehyde, and a metal ion. Orthogonal imine bond and iron (II) coordination generate a single combination of chiral elements, while configurationally stable ...

Enantio- and Chemo-Selective HPLC Analysis of Silodosin on an Amylose-Based Chiral Stationary Phase

Molecules
A direct enantio- and chemo-selective high-performance liquid chromatographic method was developed for determining the enantiomeric impurity of the chiral active pharmaceutical ingredient silodosin. The simultaneous separation of enantiomers of silodosin

Intermolekulare, Enantioselektive Nickel‐Katalysierte Arylierung von Nicht‐Aktivierten C(sp3)–H Bindungen

Angewandte Chemie, EarlyView.
Ni: neue Lösung für asymmetrische C(sp3)‐H‐Aktivierung. Die stereoselektive Synthese vollständig kohlenstoffsubstituierter quartärer Stereozentren gelingt durch eine enantioselektive C(sp3)‐H‐Arylierung unter Verwendung eines Ni‐Katalysators auf der Basis eines BINOL‐Derivaten.

Reaction-noise induced homochirality

, 2006
Starting from the chemical master equation, we employ field theoretic techniques to derive Langevin-type equations that exactly describe the stochastic dynamics of the Frank chiral amplification model with spatial diffusion.
