Abstract

By Swern oxidation of the hydroxamic acid 3, prepared from the homochiral imidazolidin-2-one 1, the transient C-nitroso derivative 4 is obtained, and its cycloaddition to either cyclohexadiene or cyclopentadiene proceeds with high diastereoselection, owing to the conformational stability of 4. The stereochemical outcome of the reaction is determined from 1H NMR data and further confirmed by the specific rotation value of 7, obtained by cleavage of the major cycloadduct 5a.
