Control of Helix Screw‐Sense Preference in Dynamic Foldamers of meso Symmetry Built From Chiral Monomeric Units

Angewandte Chemie, EarlyView.
Sequence‐diverse meso and “near‐meso” oligourea foldamers are reported and exhibit stimulus‐responsive helix screw‐sense control governed by terminal‐group desymmetrization and sequence‐encoded helix stability. ABSTRACT Meso oligoureas are dynamic hydrogen‐bonded foldamers capable of reversible helix polarity inversion but have so far been limited to ...

Click‐Spaltung quartärer Anilinium‐Tetrazine ermöglicht Kaskadenaufbau multifunktioneller biomolekularer Gerüste

Angewandte Chemie, EarlyView.
Die Click‐Chemie hat sich von dem Aufbau kovalenter Bindungen hin zum Spalten von Bindungen weiterentwickelt. Hier wird über einen Kaskaden‐Aufbau berichtet, der diese Verfahren kombiniert, um multifunktionale biomolekulare Gerüste in einer modularen Ein‐Topf‐Reaktion aufzubauen.

Chemoenzymatic Synthesis of 6‐Sulfo Sialyl Lewisx Containing Glycans to Probe the Receptor Specificity of MERS Coronavirus

Angewandte Chemie, EarlyView.
A chemoenzymatic methodology is described that provided a panel of 6‐sulfo sialyl Lewisx‐containing glycans that were probed for receptor specificity of MERS‐CoV. Although the fucoside of 6‐sulfo‐SLex does not directly interact with the spike, it pre‐organizes the molecule into a conformation to allow a salt bridge between the sulfate and the ...

Chiroptical Switching by Stereoselective Photochemical Sigmatropic Rearrangements: Experimental Realization of Calderoselectivity

Angewandte Chemie, EarlyView.
Calderoselectivity is established as a stereochemical principle for sigmatropic rearrangements. A homoannulene‐based chiroptical photoswitch undergoes a photochemical [1,11] sigmatropic rearrangement with control of the acyl movement on top of the cyclic π system.
