Abstract

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.

Keywords: Dendrimers; Chiral synthons; Binaphthols.
