Synthesis of Macrocycles Comprising 2,7-Disubstituted Naphthalene and Polyamine Moieties via Pd-catalyzed Amination

Abstract

Abstract The Pd-catalyzed reaction of equimolar amounts of 2,7-dibromonaphthalene and various polyamines led to the formation of the macrocycles comprising one naphthalene and one polyamine moieties. The same reaction also gave cyclodimers and cyclotrimers as by-products. Application of excess 2,7-dibromonaphthalene provided N,N′-bis(7-bromonaphth-2-yl)oxadiamine which was used for the synthesis of macrocycles with two naphthalene and two oxadiamine fragments.
