Upon treatment with Nail in DMF the homoallylic ethers lag and the amine lh undergo a rearrangement into the trisubstituted (E)-olefins 2a-h. Experiments with isotopically labelled forms of la and lb show that the [1,3]-shift is cleanly intramolecular and proceeds predominantly in the suprafacial mo
The high-Γeld 1H NMR analysis of 3-substituted camphors with OH, OMe, SMe, NHMe, and Me substit-NMe 2 uents at endo and exo positions, and also with an oxo substituent, is reported. The substituent-induced chemical shifts (SCS) obtained for these difunctional systems, including those from previous w
