Van Luppen, J. J. published the artcileNMR study on trapping techniques to deduce the conformations of 1-alkyl-3-hydroxypiperidines, Product Details of C7H15NO, the publication is Organic Magnetic Resonance (1982), 18(4), 199-206, database is CAplus.
The conformational equilibrium of the title compounds [I; R = H, Me, Et, Pr, Bu, CHMe2, CHMeEt, (CH2)4Me, CHMePr] was examined in hexane and H2O. The most reliable results were obtained by conformational trapping in D2SO4/D2O and anal. by 1H and 13C NMR. In an apolar solvent, the conformation with an axial group always predominates (69%). In aqueous acid solution of pH 5 the same conformation predominates (56%); in aqueous base of pH â?1 the axial-OH conformer accounted for only 43% of the mols. The results were compared with those obtained by other methods, e.g. IR.
