S. Cerezo et al., Preparation of nitrogen-containing 15-membered triolefinic macrocycles: (E,E,E)-1,6,11-tris(arylsulfonyl)-1,6,11-triazacyclopentadeca-3,8,13-trienes, EUR J ORG C, (2), 2001, pp. 329-337
Three routes to (E,E,E)-1,6,11-tris(arylsulfonyl)-1,6,11-triazacyclopentade
ca-3,8,13-trienes are described. Optimization of the preparation of key int
ermediates has opened the way to efficient synthesis of a broad variety of
15-membered, nitrogen-containing triolefinic macrocycles.
