Abstract
As part of a program directed toward the development of new families of chiral nucleophilic catalysts and new classes of chiral ligands, we have begun to explore the chemistry of 2- substituted heterocycles that are π-bound to transition metals (eg, 1). 1 Such complexes are chiral by virtue of the presence of MLn and the differentiation of R from H, and the asymmetric environment around the Lewis-basic heteroatom can readily be “tuned” by ...
