Mirror symmetry breaking with limited enantioselective autocatalysis and temperature gradients: a stability survey [PDF]

Phys. Chem. Chem. Phys., 2013, Advance Article, 2012
We analyze limited enantioselective (LES) autocatalysis in a temperature gradient and with internal flow/recycling of hot and cold material. Microreversibility forbids broken mirror symmetry for LES in the presence of a temperature gradient alone. This symmetry can be broken however when the auto-catalysis and limited enantioselective catalysis are ...

Enantioselective Total Synthesis of Multifidene, a Sex Pheromone of Brown Algae

Organics, 2022
The total synthesis of multifidene, a sex pheromone found in brown algae, is described. The synthesis features the highly enantioselective and diastereoselective addition reaction of an aldehyde to a nitroolefin in the presence of a Hayashi–Jørgensen ...

Chiral separation by enantioselective liquid–liquid extraction [PDF]

, 2011
The literature on enantioselective liquid–liquid extraction (ELLE) spans more than half a century of research. Nonetheless, a comprehensive overview has not appeared during the past few decades.

Controlled enantioselective orientation of chiral molecules with an optical centrifuge [PDF]

Phys. Rev. Lett. 122, 223201 (2019), 2019
We report on the first experimental demonstration of enantioselective rotational control of chiral molecules with a laser field. In our experiments, two enantiomers of propylene oxide are brought to accelerated unidirectional rotation by means of an optical centrifuge.

Structure Elucidation, Total Synthesis, Antibacterial In Vivo Efficacy and Biosynthesis Proposal of Myxobacterial Corramycin**

Angewandte Chemie International Edition, Volume 61, Issue 51, December 19, 2022., 2022
Corramycin is a novel natural product produced by the myxobacterium Corallococcus coralloides. The structure, extraordinary total synthesis and biosynthesis of the antibiotic is described for the first time. Its promise as an in vivo septicemia model, the absence of cross‐resistance with commonly used antibiotic classes, and the lack of cytotoxicity ...

Palladium-catalyzed asymmetric carbene coupling en route to inherently chiral heptagon-containing polyarenes

Nature Communications
Developing facile and direct synthesis routes for enantioselective construction of cyclic π-conjugated molecules is crucial. However, originate chirality from the distorted structure around heptagon-containing polyarenes is largely overlooked, the ...

Observation of persistent orientation of chiral molecules by laser field with twisted polarization [PDF]

Phys. Rev. A 101, 021403 (2020), 2019
Molecular chirality is an omnipresent phenomenon of fundamental significance in physics, chemistry and biology. For this reason, search for novel techniques for enantioselective control, detection and separation of chiral molecules is of particular importance.
