摘要
在新型多分枝大分子Dendrimers的合成研究中,设计和合成适当的分支侧链是其关键之一,为了更有效的合成这种多分枝大分子,作者设计了4个新的分支侧链,并分别以丙二酸二乙酯和季戊醇为原料,经2~4步反应将其合成,其结构经IR和1HNMR光谱等确证。与文献报道的分支侧链相比,存在着成醚分枝化程度高和空间位阻小等特点。
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.
