Chemoselective Polyalkylations of Phosphorus‐Containing Dendrimers

At the core, at the core and at the surface, within the cascade structure, or within the cascade structure and at the surface are different ways in which the dendrimers described here can be selectively alkylated. These phosphorus-containing dendrimers have generations of different constitution (example depicted on the right, □ and ▪ are neutral and cationic generations, respectively). Remarkably, even the core of a sixth generation dendrimer is shown to be accessible.
