Chirality Makes or Breaks Chemically Driven Self‐Assembly

Angewandte Chemie, EarlyView.
Chirality‐controlled reaction cycles: Reaction cycles are constructed to respond to the chirality (handedness) of an acylating agent. Left‐ and right‐handed aminoacyl phosphate esters modulate the structure, lifetime, and transformation of transient (thio)ester intermediates, enabling control over distinct chemical pathways using molecules that are ...

Total Synthesis of Feglymycin Using Umpolung Amide Synthesis

Angewandte Chemie, EarlyView.
A total synthesis of the antiviral feglymycin is described, leveraging enantioselective umpolung amide synthesis (UmAS). The strategic use of UmAS to prepare the aryl glycine‐rich tridecapeptide reduced hazardous amide coupling agents by 50%, and replaced asymmetric synthesis reliant on toxic transition metals by organocatalysis.

Exo‐Selective Intramolecular (4+3) Cycloadditions to Trans‐Fused Perhydroazulenes: An Asymmetric Formal Synthesis of (−)‐Pseudolaric Acid B

Angewandte Chemie, EarlyView.
We present an asymmetric formal synthesis of pseudolaric acid B, for which we developed a new family of substrates with an epoxide geminally tethered to a sidechain bearing a furan, which undergoes a TESOTf‐catalyzed intramolecular (4+3) cycloaddition to yield the trans‐fused perhydroazulene core and the requisite quaternary stereocenter of the natural

Chiral Induction and Memory via Supramolecular Deracemization

Angewandte Chemie, EarlyView.
The helical chirality of a dynamic crown‐ether switch can, by light‐ or redox‐switching to a prochiral state, be erased and subsequently stereoselectively re‐formed by relaxation in the presence of a point‐chiral ammonium guest. This unique supramolecular deracemization enables facile transfer and stable memory of chiral information. Abstract Chirality
