Abstract
Readily available chiral bis(phosphinoesters) based on d-glucose, d-mannose and d-galactose have been prepared in only two steps and in large scale starting from inexpensive commercial precursors. Their Pd complexes catalyze the asymmetric desymmetrization of meso-cyclopent-4-ene-1,3-diol biscarbamate in ee’s up to 82%.File in questo prodotto:
