149. Synthesis of Enantiomerically Pure Ferrocenes from Glycofuranosyl-cyclopentadienes, Synthetic Equivalents of (Alkoxyalkyl)fulvenes

Article abstract of DOI:10.1002/hlca.19940770620

Cyclopentadienyl C-glycosides ( = glycosyl-cyclopentadienes) have been prepared as latent fulvenes.Their reaction with nucleophiles leads to cyclopentadienes substituted with (protected) alditol moieties and, hence, to enantiomerically pure metallocenes.T
