Helicenes are organic molecules that gained widespread popularity due to their unique helical π-conjugated molecular ...

The synthesis relies on a different strategy in which the key step is a [5+2]-cycloaddition to form the oxabicyclic core of the target.

We have determined the kinetics of enantiomerization of several chiral organolithium compounds. We are using dipolar cycloaddition chemistry to access a variety of alkaloid structures. Intramolecular ...

Figure 1: The conductivity of a metallic carbon nanotube is suppressed significantly by a cycloaddition reaction with a fluorinated olefin molecule. A number of groups have exploited the ...

We also focus here on strategies that employ a click reaction, the copper-catalysed azide–alkyne cycloaddition reaction (CuAAC), to allow minimal functionalisation of natural product scaffolds with an ...

23 °C, Kp. 204 °C, n D 25 1,4854. Es ist in Wasser, Alkohol, Aceton und Ether löslich. Man erhält es durch 1,3-dipolare Cycloaddition von Stickstoffwasserstoffsäure an Acetylen. 1H-1,2,4-T. bildet ...

He is now best known as the inventor of "click chemistry", the method he developed for easily and reliably discovering new chemical function, and for the discovery of CuAAC (copper catalysed ...

2) ultraviolettes Licht besonders im Wellenlängenbereich von 250–260 nm, das eine chemische Veränderung der Nucleotidbasen der DNA, z. B. Bildung von Thymin-Dimeren durch Cycloaddition bewirkt.
