Abstract

Abstract A variety of chiral oxazolinylferrocenes are prepared from either ferrocenecarboxylic acid or cyanoferrocene and chiral β-amino alcohols. Highly diastereoselective ortho-lithiation (84≈ 99% de) of the oxazolinylferrocenes is accomplished with sec-butyllithium and the treatment of the lithiated compounds with an electrophile such as Mel, Ph 2 PCI or (PhSe) 2 gives the corresponding ortho-substituted ...
