Natural 1,3‐Dipolar Cycloadditions

Angewandte Chemie International Edition, 2015
[3+2] in the wild: Biomimetic natural product syntheses and theoretical considerations have indicated that 1,3-dipolar cycloadditions take place in nature. Now, the structure, biosynthesis, and function of a heavily modified prenylated flavin cofactor have been elucidated.

Nanoparticle‐Catalysed 1,3‐Dipolar Cycloadditions

European Journal of Organic Chemistry, 2020
The 1,3‐dipolar cycloadditions of azomethine‐ylides and ‐imines, nitrones, nitrilimines, and azides catalysed by inorganic nanoparticles are described. Emphasis is given to the nanometric catalysts involved, their structure, characterisation, and recyclability and, when remarkable, their preparation.

Boryl Azides in 1,3-Dipolar Cycloadditions

The Journal of Organic Chemistry, 2014
The 1,3-dipolar cycloaddition reaction of boron azides with alkynes has been investigated experimentally and computationally. At room temperature pinBN3 (pin = pinacolato) reacts with the strained triple bond of cyclooctyne with formation of an oligomeric boryl triazole.

1,3-Dipolare Cycloaddition

1994
Von Huisgen 1,2) wurde 1963 die 1,3-dipolare Cycloaddition 3–5) als Reaktionsprinzip zum Aufbau von Heterocyclen systematisiert. Man versteht darunter die Addition eines 1,3-Dipols 1, der aus den verschiedenen Kombinationen von Kohlenstoff-, Stickstoff- und Sauerstoffatomen bestehen kann und vier nicht dienische π-Elektronen umfast, an eine ...
