Regio- and stereoselectivity in preparation of benzene bridged bis- and tris-Troeger's bases

Article abstract of DOI:10.1135/cccc20020609

Synthetic strategy for novel multiple Troeger's base derivatives is presented. Compounds were prepared in three steps: o-nitrobenzoylation of benzene-1,2- and -1,3-diamines 3 followed by reduction of nitro and amide groups to amino functions and treatment
