Abstract
Efficient syntheses of the novel, pyrene containing branched building blocks 10, 13, 22, 25 and of a pyrene based core molecule 16 for the construction of dendrimers are reported. The main tool is a Suzuki cross-coupling.
The functional groups for further growth are amines and carboxylic acids, which were
used in an orthogonally protected fashion. It was proven that the building blocks
could be assembled to a low generation dendrimer 17.
Key words
arenas - dendrimers - cross-coupling - pyrenes - protecting groups
