    Ionic iodocarbocyclization reactions of 4-alkenyl- and 4-alkynylmalonate derivatives
    摘要:
    The cyclization reactions of dimethyl 4-alkenylmalonate derivatives la-d in the presence Of 12 and Ti(Ot-Bu)4 proceed in a highly regio- and stereocontrolled manner (5-exo cyclization and trans addition) to give (iodoalkyl)cyclopentane derivatives 2 or bicyclic lactones 3 through the displacement of the iodide of 2 by an ester group. Iodocarbocyclization reactions of dimethyl [(cycloalkenyl)alkyl]malonates 1g-i or dimethyl [(methylenecycloalkyl)alkyl]malonates 1j and 1k proceed regio- and stereoselectively to give fused ring compounds or spiro compounds, respectively, as single isomers. Similar reactions of 4-alkynyl derivatives 5 give preferentially E-iodomethylene cyclopentane derivatives 6. An ionic mechanism rather than a radical mechanism is suggested on the basis of the regioselectivity and stereospecificity of the above reactions.

  • Formation de cyclopentanes a partir de malonates δ-ethyleniques par un processus catalytique en palladium(O) stereochimie et mecanisme
    作者:Geneviève Balme、Didier Bouyssi、René Faure、Jacques Gore、Bruno Van Hemelryck
    DOI:10.1016/s0040-4020(01)88469-6
    日期:1992.1
    the enolate of a σ-ethylenic malonate with an unsaturated ioded in the presence of a Palladium(O) complex leads stereospecifically to a cyclopentane with the simultaneous formation in a trans fashion of the two carbon—carbon bonds. All the results authorize to conclude that this cyclisation occurs by nucleophilic attack of the enolate onto the double bond activated by the σ-palladic unsaturated species
    (O)配合物的存在下用不饱和处理不饱和的烯属丙二酸酯的烯醇化物导致立体定向生成环戊烷,同时以反式方式形成两个碳-碳键。所有的结果都可以得出结论,该环化是通过烯醇盐对σ-palladic不饱和物质激活的双键的亲核攻击而发生的。
