Abstract

The branched building plays a pivotal part in the study of Dendrimers. In order to synthesized Dendrimers more effectively, we designed and synthesized four new branched building blocks via 2-4 steps starting from diethyl malonate and pentaerythritol. Their structures were confirmed by IR and 1HNMR etc. They compare favourably with previous branched building blocks as regards to steric hindrance and branched effect.
