Unusual temperature effects in propene polymerization using stereorigid zirconocene catalysts.
ChemPhysChem 6(9) , 1929-33, (2005) Free Car-Parrinello molecular dynamics (CPMD) simulations of four diastereomers of the zirconium-propene complexes [{iPr(3-iPr-CpFlu)}ZriBu(C3H6)]+ (Cp=cyclopentadienyl; Flu=fluorenyl) provide valuable insight into the mechanism and stereocontrol of propene p... |

Enantioselective route from carbohydrates to cyclooctane polyols.
Org. Lett. 7(3) , 511-3, (2005) [reaction: see text] A synthetic route to select cyclooctane-1,2,3-triols and 1,2,3,4,5-pentaols has been defined. The starting materials are d-glucose or d-arabinose, and the key steps consist of a zirconocene-promoted ring contraction, a [3,3] sigmatropic r... |

Formal total synthesis of (+/-)-estrone and zirconocene-promoted cyclization of 2-fluoro-1,7-octadienes and ru-catalyzed ring closing metathesis.
J. Org. Chem. 73(16) , 6202-6, (2008) A new and diastereoselective method for the synthesis of the estrone skeleton from a substituted styrene based on sequential 3-fold use of Cp 2ZrBu 2 (oxidative addition-alkylation and two cyclization-alkylation sequences) and a ruthenium complex catalyzed RC... |

In pursuit of pestalotiopsin a via zirconocene-mediated ring contraction.
Org. Lett. 8(11) , 2429-31, (2006) [reaction: see text] An asymmetric route from the epimeric beta-hydroxy esters 4 and 5 to the densely functionalized (+)-10 and (-)-10, respectively, is described. Either cyclobutanol can be made available as the predominant product. The levorotatory antipode... |

A selective synthesis of hydroxyborate anions as novel anchors for zirconocene catalysts.
Dalton Trans. (21) , 2866-70, (2008) A new family of hydroxytris(pentafluorophenyl)borate anions [B(C6F5)3OH](-) associated with organic and aprotic cations c+ (imidazolium, pyrrolidinium and phosphonium) has been prepared by a general one-pot synthesis that implies the chloride borate analogues... |

Zirconocene-mediated synthesis of cyclobutabenzenes.
Org. Lett. 10(20) , 4469-71, (2008) A new, mild, one-pot method for the synthesis of cyclobutabenzenes by the zirconium-promoted cross-coupling reaction of aryllithium compounds and alkenyl bromides is reported. Formation of an arynezirconocene complex and its regioselective coupling with an al... |
