| Abstract;sec-Amide-type rotaxane was prepared by the use of hydrogen bonding as a driving force. Reduction of all amide groups of 2 to amino groups furnished sec-amine type rotaxane. N-Methylation of 2 afforded tert-amide type rotaxane (3). tert-Amine-type rotaxane (5) was prepared by the reduction of 4. Dynamic 1H NMR spectra showed that novel rotaxanes (3,4,5) thus obtained have higer mobility than 2 because they have no hydrogen-bonding between their ring and axis moieties. (author abst.) |
