SYNTHESIS AND PROPERTIES OF DIISOPROPYLTETRAAZABIS-(TROPOCORONAND)S AND RELATED PODANDS

The reaction of 8-isopropylbenzo[b]cyclohept[e][1,4]oxazine (3b) with a 1.2 equivalent of alpha,omega-alkanediamines (2, n=3-12) afforded di isopropyltropocoronands (4, n,n'=3-12) in a one-pot procedure, while t he reaction of 3b with an excess of 2 mainly gave isopropyltropopodand s (8)(n,n'=4-6). The reactions of 3b with omega-aminoalcohol afforded the corresponding dihydroxy podands 11. A single-crystal X-ray diffrac tion analysis of the nickel (II)-complex (12b) obtained from 4 (n,n'=5 ) was made.
