✦ Synopsis

The preparation and characterization of heteroannularly disubstituted ferrocene derivatives 2-8 are described, with a special attention given on the conformation and hydrogen-bonding of compounds 3b, 7a and 8a. Compounds 3 and 8 comprise hydroxyl group as a new hydrogen bond donor/acceptor and are precursors for preparation of organometallics in asymmetric bioconjugates with natural amino acids. Newly prepared compounds are characterized by elemental analysis, FTIR and NMR spectroscopy. The structures of compounds 1, 3b and 6a were also confirmed by X-ray crystal structure analysis.
