Photolytic Hydrophosphination: Insights Into Catalyzed and Uncatalyzed Processes

Chemistry – A European Journal, EarlyView.
Catalyst‐free photolytic hydrophosphination is demonstrated for vinyl arenes and activated alkenes in polar protic (alcohol) solvents. These reactions appear to be closed‐shell, affirming that even ambient light can impact a reaction—a potentially broad influence on even mundane reactions.

Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches

Chemistry – A European Journal, EarlyView.
We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...

Strain Release of 1‐Azabicyclo[1.1.0]butanes as a Gateway to Highly Functionalized Azetidines: New Strategies and Structural Motifs

Chemistry – A European Journal, EarlyView.
Over the past decade, the interest in azetidines has continuously risen, by virtue of their highly appealing pharmaceutical properties. Monocyclic, spirocyclic, and bridged azetidines can be accessed by leveraging 1‐azabicyclo[1.1.0]butanes as precursors.

Stereoselective Higher‐Order [10+4]‐ and [10+6] Cycloadditions Between Two Highly Unsaturated and Ambiphilic π‐Addends

Chemistry – A European Journal, EarlyView.
Aminocatalytically generated isobenzofulvenes and 3‐oxidopyridinium betaines act as ambiphilic reaction partners in orbital‐symmetry‐allowed [10+4] cycloadditions or formally symmetry‐forbidden concerted thermal [10+6] cycloadditions. The reaction furnishes three cycloadducts: one [10+4] cycloadduct and two regioisomeric [10+6] cycloadducts.
