    Synthesis of allenes via thermal cycloreversion of .alpha.-alkylidene-.beta.-lactones
    摘要:
    This paper describes the application of the solution-phase [2 + 2] cycloreversion of alpha-alkylidene-beta-lactones as a practical method for the generation of substituted allenes. Upon heating in dimethylformamide solution at 110-125-degrees-C, these unsaturated beta-lactone derivatives undergo decarboxylation to provide allenes in good to excellent yield. Alpha-alkylidene-beta-lactones are conveniently prepared via the phenylselenylation of beta-lactone enolates followed by oxidative elimination of the resulting alpha-phenylseleno derivatives. The beta-lactone starting materials are synthesized by the addition of thiol ester enolates to ketones and aldehydes according to our recently reported procedure.

  • Boraformylation and Silaformylation of Allenes
    作者:Tetsuaki Fujihara、Ayumi Sawada、Tatsuya Yamaguchi、Yosuke Tani、Jun Terao、Yasushi Tsuji
    DOI:10.1002/anie.201611314
    日期:2017.2
    The boraformylation of allenes with B2(pin)2 and a formate ester as boron and formyl source, respectively, proceeds in the presence of a copper catalyst. The reaction selectively affords the corresponding β‐boryl β,γ‐unsaturated aldehydes in good to high yields. Furthermore, the silaformylation of allenes was achieved with a formate ester and PhMe2Si−B(pin) as the silicon source.

    日期:2018.1
    A highly regio‐, diastereo‐ and enantioselective addition of 2‐acyl imidazoles or 2‐acyl pyridines with allenes promoted by Rh/Lewis acid synergistically catalytic system is described. This atom economic approach leads to the formation of the branched allylic alkylated products including acyclic quaternary all‐carbon stereogenic centres in good yields with good to excellent diastereo‐ and enantioselectivities

    between terminal allenes and aryl or styryl gold(I) carbenes generated by a retro-Buchner reaction of 7-substituted 1,3,5-cycloheptatrienes led to indenes and cyclopentadienes, respectively. These cycloaddition processes have been applied to the construction of the carbon skeleton of the cycloaurenones and the dysiherbols as well as to the total synthesis of (±)-laurokamurene B.

    日期:2015.6.1
    A rhodium‐catalyzed hydroformylation of 1,1‐disubstituted allenes is reported. Using a RhI/6‐DPPon catalyst system, one can obtain β,γ‐unsaturated aldehydes in high regio‐ and chemoselectivity. The Z‐configured product is formed with up to >95 % selectivity when unsymmetrically 1,1‐disubstituted allenes are submitted to the reaction conditions. This is the first time that these interesting building
