journal contribution
posted on 2002-10-10, 00:00 authored by Liang, Terry T.-L. Au-Yeung, Albert S. C. ChanHigh enantioselectivities have been achieved in the 1,4-addition of dialkylzincs to 2-cyclopentenone, 2-cyclohexenone, and 2-cycloheptenone
with ee values up to 99% by using chiral aryl diphosphite ligands derived from H8-binaphthol.
