    Unusual endoperoxide isomerizations: a convenient entry into 2-vinyl-2-cyclopentenones from saturated fulvene endoperoxides
    摘要:
    An unusual peroxide base-promoted isomerization is uncovered. Saturated endoperoxides derived from fulvenes give rise to 2-vinyl-2-cyclopentenones upon treatment with DBU in CH2CL2 in a one-pot reaction. This methodology is applied to a convenient synthesis of dihydrojasmone. Moreover, functional groups placed on the side chain at C-6 participate in the base-catalyzed isomerizations via conjugate attack at the enone moiety to give 2-cyclopentenones carrying oxygen heterocycles at C-2.

    Abstract The reaction of Et3Al/CH2I2 reagent with cyclopropanated spiro[2.4]hepta-4,6-diene and 6-substituted fulvenes in CH2Cl2 was found to lead to the selective formation of rearrangement products through sequential cyclopropyl-allyl rearrangement and cyclopropanation. Graphical Abstrat

  • Accessing Monosubstituted Cyclopentadienyl Rhodium(I) and Iridium(I) Complexes by a Simultaneous Nucleophilic Addition-Metalation Approach to Fulvenes
    作者:Aragorn Laverny、Nicolai Cramer
    DOI:10.1021/acs.organomet.0c00550
    日期:2020.12.28
    Despite advances in the synthesis of polysubstituted cyclopentadienyl metal complexes, the rapid access to a library of monosubstituted Cp bearing metal complexes remains challenging. A convenient and general method to access a broad range of monosubstituted cyclopentadienyl rhodium(I) and iridium(I) complexes is reported. The process involves a direct nucleo-metalation of fulvenes with widely available
    尽管在多取代的环戊二烯基金属配合物的合成方面取得了进展,但是快速获得带有单取代的Cp的金属配合物的文库仍然具有挑战性。据报道,一种方便且通用的方法可用于广泛的单取代的环戊二烯基铑(I)和铱(I)配合物。该方法涉及富勒烯与广泛可用的金属前体的直接核金属化,以高收率提供一组CpRh I(烯烃)2和CpIr I(烯烃)2配合物。发现广泛的基于氧,氮和碳的亲核试剂可胜任该方法,并提供了环戊二烯基部分的良好调节能力。

  • Kinetics and Mechanism of Pyrrolidine Buffer-Catalyzed Fulvene Formation
    作者:Paul Sieverding、Johanna Osterbrink、Claire Besson、Paul Kögerler
    DOI:10.1021/acs.joc.8b01660
    日期:2019.1.18
    Rapid synthesis of fulvenes is achieved using pyrrolidinium/pyrrolidine buffers in anhydrous acetonitrile. Time-dependent UV–vis absorption and NMR spectroscopy reveal that the rate and yield of fulvene formation depend strongly on both the presence of acid in the medium and the choice of solvent, and they are negatively affected by water. Kinetic data have been collected for various substrates, and
