Aerobic oxidative desymmetrization of meso-diols with bifunctional amidoiridium catalysts bearing chiral N-sulfonyldiamine ligands

Asymmetric aerobic oxidation of a range of meso- and prochiral diols with chiral bifunctional Ir catalysts is described. A high level of chiral discrimination ability of Cpa? -Ir complexes derived from (S,S)-1,2-diphenylethylenediamine was successfully demonstrated by desymmetrization of secondary benzylic diols such as cis-indan-1,3-diol and cis-1,4-diphenylbutane-1,4-diol, providing the corresponding (R)-hydroxyl ketones with excellent chemo- and enantioselectivities. Enantiotopic group discrimination in oxidation of symmetrical primary 1,4- and 1,5-diols gave rise to chiral lactones with moderate ees under similar aerobic conditions.

Separation and Characterization of All Configurational Isomers by Enzymatic Discrimination of Each Chiral Function

An enzymatic method for simultaneous performance of separation and analysis of (meso/racemic)-diesters, i.e. 1,4-bis(1-acetoxyethyl)benzene (3a) and 1,4-bis-(1-acetoxyisopropyl)benzene (3b), was demeonstrated. Key Words: lipases; separation; meso and racemic mixtures; p-disubstituted benzenes; chiral centers
