Abstract

Chiral cyclophanes were synthesized by cyclodimerization of 2,7-diaza-1,2,3,6,7,8-hexahydropyrene N-acylated with l-amino acids through stepwise nucleophilic aromatic substitution of 1,5-difluoro-2,4-dinitrobenzene.

Simulations were performed with MMFF force field in chloroform implemented in MacroModel; 20000 conformers were collected for each compound.
