, p. 181 - 184 (2004)
(Matrix presented) A series of tetralactam macrocycles having different substituents were prepared, and their binding affinities for an adipamide guest were investigated in CDCl3 by 1H NMR titrations. The association constants strong
Template synthesis of rotaxanes with carbamate-linked axles
Braun, Oliver,Huenten, Annette,Voegtle, Fritz
, p. 542 - 547 (2007/10/03)
Proceeding from diisocyanates 4 and 10-13, (4-hydroxyphenyl)triphenylmethane 14 and tetralactame macrocycles 1, 2 and 9 the threading synthesis of rotaxanes 16-21 containing carbamate units in the axle is described. In addition to aromatic diisocyanates aliphatic ones are firstly introduced as building blocks in rotaxane chemistry. The template synthesis of the new tetralactame macrocycle 9 with a pyridine unit is presented. It is used as wheel in a rotaxane synthesis towards the carbamate-linked rotaxane 21.
