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 ...

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‐Dipolar Cycloadditions to Strained Olefins

Helvetica Chimica Acta, 1979
AbstractThe Bredt olefins bicyclo [3.3.1]non‐1‐ene (2), bicyclo [4.2.1]non‐1 (8)‐ene (3), and bicyclo [4.2.1]non‐1 (2)‐ene (4) react rapidly with 1,3‐dipoles such as diazomethane, phenyl azide, and mesitonitrile oxide to yield mixtures of two regioisomeric cycloadducts 10, 11 and 12, respectively.
