Chiral Anion Dependent Inversion of Diastereo- and Enantioselectivity in Carbonyl Crotylation via Ruthenium Catalyzed Butadiene Hydrohydroxyalkylation

The ruthenium catalyst generated in situ from H(2)Ru(CO)(PPh(3))(3), (S)-SEGPHOS and a TADDOL-derived phosphoric acid promotes butadiene hydrohydroxyalkylation to form enantiomerically enriched products. Notably, the observed diastereo- and enantioselectivity is opposite of that observed using BINOL...
