Bradshaw The Chemistry of Heterocyclic Compounds, Aza-Crown Macrocycles. A series of new chiral macrocycles containing the trans-1,2-diaminocyclohexane (DACH) subunit and arene- and oligoethylene glycol-derived spacers has been prepared in enantiomerically pure form.

Four of the macrocycles have been characterized by X-ray crystallography, which reveals a consistent mode of intramolecular N–HN hydrogen bonding and conformational variations about the N Cited by: The novel bibrachial lariat ethers (BiBLEs) 3a-d with neutral side chains were preparedby reaction of the corresponding aza-crown macrocycles 1a-b with ethyl chloroacetate and chloroacetamide.

macrocycles due to their larger cavity size compared to the membered cycles. The structures of macrocycles were confirmed by CHN/O analysis, IR, 1H NMR, 13C NMR and mass spectrometry.
