Synthesis of Macrobicycles Comprising 2,7-Diaminonaphthalene Moiety via Palladium-Catalyzed Amination Reaction
摘要:
An original synthetic approach to bismacrocyclic ligands bearing naphthalene moiety was developed. First, the macrocycles comprising 2,7diaminonaphthalene fragment were reacted with 2,7-dibromonaphthalene, 4,4'dibromobiphenyl or bromobenzyl bromide affording corresponding NN'bis(bromoaryl) or N,N'-bis(bromobenzyl) substituted macrocycles. Pd-catalyzed macrocyclization of these compounds with a wide range of di- and polyamines led to a series of new macrobicyclic ligands. The yields of the macrobicycles are strongly dependent on the nature of starting compounds, reaching 35% in some cases.

The Pd-catalyzed reaction of equimolar amounts of 2,7-dibromonaphthalene and various polyamines led to the formation of the macrocyclescomprising one naphthalene and one polyaminemoieties. The sa...
