Preparation of nitrogen-containing 25-membered pentaolefinic macrocycles: (E,E,E,E,E)-1,6,11,16,21-penta(arylsulfonyl)-1,6,11,16,21- pentaazacyclopentacosa-3,8,13,18,23-pentaenes

A stepwise preparation of a series of nitrogen-containing 25-membered pentaolefinic macrocycles is presented. The corresponding arenesulfonamides and trans-1,4-dibromo-2-butene served as precursors for the synthesis. Georg Thieme Verlag Stuttgart.

Preparation of nitrogen-containing 15-membered triolefinic macrocycles: (E,E,E)-1,6,11-tris(arylsulfonyl)-1,6,11-triazacyclopentadeca-3,8,13-trienes

Three routes to (E,E,E)-1,6,11-tris(arylsulfonyl)-1,6,11-triazacyclopentadeca-3,8,13-trienes are described. Optimization of the preparation of key intermediates has opened the way to efficient synthesis of a broad variety of 15-membered, nitrogen-containing triolefinic macrocycles.

Palladium(0) complexes of a 15-membered macrocyclic triolefin as a recoverable catalyst - Monomer- and polystyrene-anchored versions

Preparation of the 15-membered cycle (E,E,E)-1,6,11-tris[(2,4,6- triisopropylphenyl)sulfonyl]-1,6,11-triazacyclopentadeca-3,8,13-triene (8) is reported. This cyclic triolefin forms a stable Pd°complex 9 which catalyzes several cross-coupling reactions and
