Jary, Walther G.; Baumgartner, Judith published the artcile< Asymmetric dihydroxylation reactions leading to novel chiral ferrocene derivatives>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is Sharpless asym dihydroxylation ferrocenyl alkene; ferrocene chiral dihydroxyalkyl derivative asym preparation; osmium catalyzed asym dihydroxylation ferrocenyl alkene.
Several ferrocenyl alkenes were used as starting materials for asym. dihydroxylation reactions. Although they turned out to be unreactive employing Sharpless’ standard conditions, by systematic variation of the reaction conditions the desired novel ferrocenyl diols could be obtained in good yields and in enantiomeric excesses up to >99%. E.g., (1-propenyl)ferrocene was added to a homogeneous MeCN/H2O solution of K3Fe(CN)6, K2CO3, K2OsO2(OH)4 and (DHQD)2PYR ligand to give 1-[((1S,2R)-cis-1,2-dihydroxy)propyl]ferrocene in 99% yield (97% e.e.).
