15 and 30-Membered polyolefinic macrocycles. Periphery modification by aromatic nucleophilic substitution of fluorine
摘要:
Tris[(4-fluorophenyl)sulfonyl]-1,6,11-triazacyclopentadeca-3,8,13-triene is a pivotal 15-membered triolefinic macrocycle from which a vast array of different derivatives are prepared by substitution of fluorine atoms. (C) 2002 Elsevier Science Ltd. All rights reserved.

Improved conditions are reported for the stoichiometric reaction of nitrogen, oxygen, and sulfur nucleophiles with weakly activated 4-fluorophenylsulfonamides.
A new family of phosphorus dendrimers containing at the same time triolefinic 15-membered azamacrocycles as core and on the surface have been prepared. The new macromolecules contain up to thirteen macrocycles with potential metal coordinating ability. dendrimers - phosphorus - macrocycles - heterocycles - sulfonamides
