ChemInform Abstract
Comparisons of the enantioselectivities achieved in the protonation of lithium enolates derived from lactones (I) as well as 3- heteroanalogues (cf. foregoing papers) with chiral proton sources indicate, that definite structure-selectivity correlations can not be derived both for the enolates and the proton source.
