Synthesis and proton nuclear magnetic resonance spectra of diastereoisomeric ethyl 3-hydroxy-2-methyl-3-(p-substituted phenyl)butyrates
Abstract
A series of erythro- and threo-ethyl 3-hydroxy-2-methyl-3-(p-substituted phenyl)butyrates has been prepared The 1H n.m.r. spectra of these compounds and their use in assigning diastereoisomeric configurations are discussed
