Rapid synthesis of polyester dendrimers

Aryl polyester dendrimers and dendrons have been prepared by using 'branched monomer strategies', in which the surface and the focal point of the multi-branched monomer have been protected with two different kinds of protective group. The protective group for the focal point was stable during deprotection of the surface. Different wedges could be attached to the multi-branched monomers to form large dendrons whilst active dendrons could be attached to different cores to form various dendrimers with different wedges and different cores.
