Axially chiral synthons for chiral dendrimer construction based on 2,2'-dihydroxy-1,1'-binaphthalene-3,3'-dicarboxylic acid were prepared, namely, chiral connecting units (3, 6, 8), chiral branching units (10, 12, 14), and chiral surface units (5, 17). Regioselective chloromethylation of methyl 3'-acetoxymethyl-2,2'-dimethoxy-1,1'-binaphthalene-3-carboxylate (7) was also studied.
基于2,2'-二羟基-1,1'-联萘-3,3'-二羧酸的手性树状分子构建,制备了轴向手性合成单元,包括手性连接单元(3、6、8)、手性分支单元(10、12、14)和手性表面单元(5、17)。还研究了甲基3'-乙酰氧甲基-2,2'-二甲氧基-1,1'-联萘-3-羧酸甲酯(7)的区域选择性氯甲基化。
