Synthesis of 2,3-disubstituted norbornadienes

Various 2,3-disubstituted norbornadienes that can hardly be made by the traditional Diels-Alder method were synthesized by double lithium halide exchange of 2,3-dibromonorbornadiene in moderate to good yields.

Intramolecular 1,3-dipolar cycloadditions of norbornadiene-tethered nitrile oxides

Efficient routes to the synthesis of norbornadiene-tethered nitrile oxides have been developed, and their intramolecular 1,3-dipolar cycloadditions were studied. The cycloadditions occurred in good yields for a variety of substrates and were found to be highly regio- and stereoselective, giving single regio- and stereoisomers in most cases.

Norbornadiene-bridged diarylethenes and their conversion into turn-off fluorescent photoswitches

We describe the synthesis and characterization of novel diarylethene photoswitches that contain a norbornadiene bridge and operate as p-type positive photochromes. One of the double bonds of norbornadiene is furthermore utilized to attach a fluoresceine tetrazine by an iEDDA cascade reaction, thereby forming a turn-off mode fluorescent photoswitch.

Diaryl-substituted norbornadienes with red-shifted absorption for molecular solar thermal energy storage

Red-shifting the absorption of norbornadienes (NBDs), into the visible region, enables the photo-isomerization of NBDs to quadricyclanes (QCs) to be driven by sunlight. This is necessary in order to utilize the NBD-QC system for molecular solar thermal (MOST) energy storage. Reported here is a study on five diaryl-substituted norbornadienes. The introduced aryl-groups induce a significant red-shift of the UV/vis absorption spectrum of the norbornadienes, and device experiments using a solar-simulator set-up demonstrate the potential use of these compounds for MOST energy storage. the Partner Organisations 2014.

Enantiomeric discrimination in a reiterative domino coupling process: CuI-mediated Syn cyclotrimerization of racemic polycyclic trimethylstannyl bromonorbornadienes

The challenge to generate all-syn architecture has prompted the synthesis of syn cyclotrimers 2 from racemic bromotrimethylstannyl polycyclic alkenes 1. The syn-selective CuI-catalyzed cyclotrimerization process is both regio- and chemo-selective.
