Au(PPh(3))Cl-AgSbF(6)-catalyzed rearrangement of propargylic 1,3-dithiane leads to the formation of 8-membered dithio-substituted cyclic allenes, which are remarkably stable.
An effective phosphine-catalyzed protocol has been established for the syntheses of 1,3-diketones and nitriles from alkynones with oximes as hydroxide surrogates. This method features the use of a phosphine catalyst, compatibility with various functional groups and ambient temperature, which makes this approach very practical. A plausible mechanism was proposed.
Synthesis of Phosphonylated and Thiolated Indenones by Manganese(III)-Mediated Addition of Phosphorus- and Sulfur-Centered Radicals to 1,3-Diarylpropynones
Phosphorus- or sulfur-centered radicals generated from the reaction of manganese (III) acetate with dialkyl phosphonates or arylthiols undergo selective additions to conjugated alkynes followed by cyclization and rearomatization to afford 2-phosphonyl- or 2-thioaryl-substituted indenones in fair to good yields.
Copper-catalyzed [4 + 1] cycloaddition reaction of α,β-acetylenicketones with α-diazo esters offers an efficient, direct route to highly substituted furans. The reaction conditions and the scope of the process are examined, and a possible mechanism is proposed.
