    important biologically active compounds. Synthesis of a series of tricyclic benzopyrans derivatives via N-Heterocyclic carbene (NHC) catalyzed annulation of enals to α-methylidenetetralones/chromanones is described. This reaction afforded the benzopyrans in high yield with aromatic as well as aliphatic enals.

    DOI:10.1016/s0040-4039(00)92884-3
    日期:1980.1
    Siloxycyclopropanes were quantitatively converted to β-acetoxymercuri ketones by the reaction with mercuric acetate. Successive treatment with palladium chloride or palladium chloride/carbon monoxide gave α-methylene ketones or γ-ketoesters, respectively, in good yields.

    Reactions of sulfonium methylides attaches to a 5- or 6-membered cycloalkanone undergo the ring-fission as a major reaction course to give α-methylene-ω-(phenylthio)carboxylates, whereas sulfonium methylides attached to a larger ring give α-methylenecycloalkanones predominantly. Reactions of the acyclic compounds are also examined

    DOI:10.1016/s0040-4039(00)74251-1
    日期:1992.7
    TMS ethers of 1-alkenyl-1-cycloalkanols readily rearranged to the ring expanded β-mercurio cycloalkanones via mercurinium ions, which could be converted into α-methylene cycloalkanones through elimination and further one carbon expanded cycloalkanones via free radical chain reactions.
    1-烯基-1-环烷醇的TMS醚很容易通过uri离子重排成扩环的β-巯基环烷酮,可以通过消除将其转化为α-亚甲基环烷酮,还可以通过自由基链反应将其转化为一个碳扩环的环烷酮。
