Single enantiomer, chiral donor-acceptor metal complexes from bisoxazoline pseudoracemates.

[structure: see text] Single enantiomer, chiral donor-acceptor metal complexes were synthesized via the self-discriminating zinc(II) complexation of a pseudoracemic mixture of donor/acceptor-substituted bisoxazoline derivatives.

A two-stage iterative process for the synthesis of poly-oxazoles.

[reaction: see text]. Methodology has been developed to prepare bis-oxazoles via a two-stage iterative process. The sequence begins with C(2)-chlorination of a lithiated oxazole using hexachloroethane.
