Dynamics and Conformational Stability of Chiral Bay‐Phenolate‐Substituted Twisted Octaazaperopyrenedioxides (OAPPDOs)

Chemistry – A European Journal, EarlyView.
Chiral octaazaperopyrenedioxide (OAPPDO) fluorophores were obtained by functionalizing with BINOL and related fragments bridging the bay position. They possess conformational flexibility but remarkable thermal stability with respect to racemization of the central chromophore, which allowed the study of their chiroptical properties, including circular ...

Dual‐Mode Thio‐MacMillan Organocatalysts: Stereoselective Diels–Alder Reactions or Sacrificial Self‐Cyclization to N‐Bridged Bicyclic Lactams

Chemistry – A European Journal, EarlyView.
The study of the Diels–Alder reaction of cinnamaldehyde and cyclopentadiene, catalyzed by chiral imidazolidine‐4‐thiones, led to the discovery of a highly regio‐ and stereoselective Michael‐addition and consecutive ring closure. Here, the imidazolidine‐4‐thione not only catalytically activates cinnamaldehyde but also participates as the nucleophile to ...

One‐Pot Transition‐Metal‐Free Methods for the Synthesis of All Three Bonds of the Alkyne's Triple Bond

Chemistry – A European Journal, EarlyView.
One‐pot transition‐metal‐free methods for the synthesis of all three bonds of the alkyne's triple bond are reviewed. After analysis of several named reactions and discussion of improvements, recent advances in the synthesis of alkynes are discussed. Each section contains a proposed reaction mechanism and analysis of the strengths and weaknesses of the ...
