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.

Extended dipolar cycloadditions

Journal of the Chemical Society, Perkin Transactions 1, 1975
Whilst the simple azomethine imine (5) undergoes the expected 1,3-dipolar cycloaddition to acetylenic esters, the extended azomethine imines (1) undergo 1,5-rather than 1,3-dipolar cycloaddition to give benzo[c][1,2,5]-triazepino[1,2-a]cinnolines (2), possibly by a stepwise mechanism 2-Alkyl-2λ5σ3-naphtho[1,8-de]triazines (12) and 2λ4σ2-naphtho[1,8-cd ...

1,11-Dipolar cycloaddition

Journal of the Chemical Society, Chemical Communications, 1972
2-Methylnaphtho[1,8-de]triazine undergoes 1,11-dipolar (12π+ 2π) cycloaddition to acetylenic esters to give 2-methylacenaphtho[5,6-de]triazines, after spontaneous dehydrogenation.
