The protonation features of two optically active 22-membered hexaazamacrocycles possessing one (L1) or two (L2) (R,R)-cyclohexane-1,2-diamine moieties have been studied by means of potentiometric 1 H-and 13 C-NMR techniques. This study allows the determination of the basicity constants and the stepw

Optically active exo-exo-2,3-camphanediol (CPO) (3) was synthesized from (+)-camphor. Chiral polymers poly(CP0-co-TDI) (6) and poly(CP0-co-IPDI) (7) were synthesized by the step polymerization of chiral compound CPO (3) with toluene-2,4-diisocyanate (TDI) and isophorone diisocyanate (IPDI).

Two new C2 and D2 symmetrical dioxatetraaza 18-membered macrocycles [(R,R)-1 and (S,S,S,S)-2] are efficiently synthesized in enantiomerically pure forms by a chemoenzymatic method starting from (+/-)-trans-cyclohexane-1,2-diamine. The protonation constants and the binding constants with different ch
