    Catalytic Enantioselective 1,4-Iodofunctionalizations of Conjugated Dienes
    摘要:
    The first catalytic enantioselective 1,4-iodofunctionalizations of conjugated dienes have been developed. Starting from beta,gamma,delta,epsilon-unsaturated oximes and 4-Ns hydrazones, these N-iodosuccinimide-mediated reactions are catalyzed by newly modified tertiary aminothiourea derivatives and furnish Delta(2)-isoxazoline and Delta(2)-pyrazoline derivatives, respectively, containing an (E)-allyl iodide group at the quaternary stereogenic center generally in high yield and with excellent enantioselectivity (up to 98.5:1.5 er).

  • Palladium-Catalyzed Regioselective [5 + 1] Annulation of Vinyl Aziridines/Epoxides with ClCF<sub>2</sub>COONa

    regioselective [5 + 1] annulation reactions of vinyl aziridines/epoxides with ClCF2COONa have been developed. Significantly, vinyl aziridines/epoxides act as heteroatom-containing five-atom synthons, and commercially available and cheap ClCF2COONa acts as the source of carbonyl serving as a difluorocarbene precursor. This protocol provides an efficient and practical method for the synthesis of δ-lactams and

  • Rh–IndOlefOx catalyzed conjugate addition/Heck-type coupling of organoboronics to a lactam or a lactone
    作者:Noora Kuuloja、Matti Vaismaa、Robert Franzén
    DOI:10.1016/j.tet.2012.01.040
    日期:2012.3
    Four indole-olefin-oxazoline (IndOlefOx) ligands were synthesized and evaluated in Rh-catalyzed reactions between organoboronics and a lactam or a lactone. In addition to the expected conjugate addition products, the formation of significant amounts of Heck-type products was observed. The scope and limitations of these reactions were investigated.

  • Synthesis of 4-Aryl-Substituted Butenolides and Pentenolides by Copper-Catalyzed Hydroarylation
    作者:Yoshihiko Yamamoto、Naohiro Kirai
    DOI:10.3987/com-09-s(s)8
    日期:——
    We have investigated the effect of the type of protecting group used and the tether length of 4- and 5-hydroxy-substituted 2-alkynoates on the yields and selectivity of the product of hydroarylation. The use of methyl, methoxymethyl, and tert-butyldimethylsilyl (TBS) as protecting groups increased the total yield of the products. While the protected 4-hydroxy-2-butynoates afforded products formed from two or more alkyne substrates, 5-hydroxy-2-pentynoate derivatives exclusively yielded 1:1 adducts. These facts suggest that the product selectivity depends on the distance of the alkoxy group from the alkyne moiety rather than the type of the protecting group. Among the protecting groups used in this study, the TBS group was found to produce butenolides and pentenolides in good total yields via the one-pot hydroarylation/lactonization.

    Several types of chiral hetero‐ and carbocyclic compounds have been synthesized by using the asymmetric hydrogenation of cyclic alkenes. N,P‐Ligated iridium catalysts reduced six‐membered cyclic alkenes with various substituents and heterofunctionality in good to excellent enantioselectivity, whereas the reduction of five‐membered cyclic alkenes was generally less selective, giving modest enantiomeric
