On the relationship between intramolecular hydrogen abstraction by alkoxyl radicals and deshielding by the corresponding hydroxy-groups as indicated by nuclear magnetic resonance
Abstract
The 1H n.m.r. spectra of various steroids and triterpenoids and their hydroxy-derivatives have been studied. It is shown that a consideration of deshielding by hydroxy-groups can provide valuable information on the likely course of intramolecular hydrogen abstraction reactions of alkoxyl radicals.
