Complete assignment of the 1H and 13C NMR spectra of a pentacyclo [5.4.0.02,6.03,10.05,9]undecane derivative

Abstract: The production of compounds derived from intramolecular photocgcloaddition reactions upon Diels-Alder adducts has received considerable attention, but assignment of the NMR spectra of the photoaddition products has proved problematic, rendering structural determination difficult. This paper reports the complete assignments of the proton and carbon NMR spectra of 11.1 I-dimethoxypentacyclol S.~.0.02~6.0"".0".9 lundecan-&one and the assignment of the spectra of pentacyclo 1 5.4.0.02~6.0'~'0.05~9

“…Pentacyclo[6.3.0.0 2,6 .0 3,10 .0 5,9 ]undecane (trishomocubane) was first reported by Eaton et al in 1968, as a keto derivative. 1 Later, Underwood and Ramamoorthy were successful in synthesizing the underivatized C 11 H 14 polycyclic hydrocarbon, for which they proposed the trivial name trishomocubane (1) (Fig.…”

“…2 To whom all corespondence should be addressed; e-mail: kruger@ ukzn.ac.za [2,3,5,[13][14][15][16][17], similar studies on the intrinsically chiral [8] trishomocubane systems [6,7,[18][19][20] are somehow neglected. Various authors [16,[21][22][23] have commented on the difficulty of NMR elucidation of these cage compounds. The trishomocubane skeleton also seems to be more difficult to elucidate by NMR methods due to higher symmetry (two almost identical CH 2 groups compared to one distinct CH 2 on the PCU-skeleton).…”

“…Although NMR elucidation of the pentacyclo-undecane cage system is well studied [9,[22][23][24][25][26][27][28], the elucidation of these cage systems remains very complex due to major overlap of proton signals and some carbon signals of the cage skeleton. The previous reported [9] NMR elucidation of the PCU hydantoin (5) was useful and the same numbering system was also adopted.…”
