Optimal stereoselectivities in the OsO4-catalyzed dihydroxylation of chiral gamma-amino alpha,beta-unsaturated esters are achieved by the proper choice of the protective groups at nitrogen [t-butoxycarbonyl (Boc) versus dibenzyl] and the correct choice of the chiral ligand of the catalyst (AD-mix-alpha versus AD-mix-beta).
