Abstract

New chiral bis(phosphinoamides) based on glucose 1G and mannose 1M have been prepared. Their Pd complexes catalyze the asymmetric desymmetrization of meso-cyclopenten-2-ene-1,4-diol biscarbamate in high ee’s (up to 97%). Glucose and mannose moieties selectively promote formation of the opposite enantiomers, as a consequence of inverted steric motifs around the metal center.
