Abstract
Chiral 1,2-bis(phosphetano)benzenes are readily prepared from accessible, o ptically pure 1,3-diol cyclic sulfates. Their ruthenium complexes catalyze the enantioselective hydrogenations of functionalized carbonyls with modera te-to-high enantiomeric excesses. High levels of diastereo- and enantiosele ctivity are achieved, especially in the hydrogenation of beta-diketones to the corresponding anti-1,3-diols.
