✦ Synopsis

Total assignment of "C and 'H NMR spectra of the new compounds 1-cyano-and 1-phenyl-substituted 3,fdimethyl-2-thiatricycl0[3.2.l.l~~~]nonane 2,Z-dioxide was achieved using the concerted application of two-dimensional homonuclear and heteronuclear chemical shift correlations. This unequivocal structure determination rules out the formation of a six-membered ring during the intramolecular cyclization of the a-sulphonyl-C-centred radical originating from 5-endo-isopropylsulphonyl-5-exo-substituted norbornene.
