Boron-containing building blocks are among the most prominent starting materials in
several transformations based on their wide range of synthetic applications. Over
the last decade various cycloaddition reactions were reported where boron-containing
1,3-dienes or boron-containing dienophiles were used. Combined with the broad follow-up
chemistry, target-oriented as well as diversity-oriented syntheses could be established.
