Abstract

C 2 -Symmetric 1,1′,2,2′-tetrasubstituted ferrocene derivatives are prepared in high yields from chiral 1,1′-bis(oxazolinyl)ferrocenes via diastereoselective o , o '-dilithiation with sec -butyllithium followed by nucleophilic substitution. 1,1′-Bis(oxazolinyl)ferrocenes were prepared from 1,1′-ferrocenedicarbonyl dichloride and enantiomerically pure aminoalcohols via the corresponding bis(β-hydroxylamide)s and dimesylates as intermediates.

Abstract

To elucidate the structural requirements for the endotoxic and antagonistic activities of lipid A derivatives, we have focused on the effects of the acyl moieties and acidic groups at the 1- and 4′...
