    A Parallel Approach to 7-(Hetero)arylpyrazolo[1,5-a]pyrimidin-5-ones
    摘要:
    A modular, two-pot assembly of 7-arylpyrazolo[1,5-a]pyrimidones from aryl/heteroaryl halides and aminopyrazoles in library format was developed. Sonogashira coupling of aryl bromides with triethyl orthopropiolate, followed by in situ orthoester hydrolysis, provides access to beta-aryl ynoates, which undergo regioselective cyclocondensation with aminopyrazoles. The ability to vary the C7 vector of 7-arylpyrazolo[1,5-cdpyrimidones in two steps using readily available (hetero)aryl halides significantly enhances synthetic access to this challenging vector.

  • Ruthenium-Catalyzed Asymmetric [2 + 2] Cycloadditions between Chiral Acyl Camphorsultam-Substituted Alkynes and Bicyclic Alkenes
    作者:Jordan Goodreid、Karine Villeneuve、Emily Carlson、William Tam
    DOI:10.1021/jo501594g
    日期:2014.11.7
    Ruthenium-catalyzed asymmetric [2 + 2] cycloadditions between chiral acyl camphorsultam-functionalized alkynes and bicyclic alkenes were examined, providing adducts with complete exo stereoselectivity in good overall yield and enantioselectivity (up to 99% and 166:1, respectively), as well as appreciable diastereoselectivity (up to 163:1). The diastereoselectivity showed dependence on the solvent and

  • Preparation of Ethyl Arylpropiolates from Aryl Iodides by Palladium-Catalyzed Cross-Coupling Reaction
    作者:Takao Sakamoto、Futoshi Shiga、Akito Yasuhara、Daishi Uchiyama、Yoshinori Kondo、Hiroshi Yamanaka
    DOI:10.1055/s-1992-26214
    日期:——
    The palladium-catalyzed cross-coupling reaction of aryl iodides with 3,3,3-triethoxy-1-propyne gave 1-aryl-3,3,3-triethoxy-1-propynes which were converted to the corresponding ethyl arylpropiolates. The arylpropiolates were also synthesized from the cross-coupling reactions of aryl iodides with 2-ethoxycarbonyl-1-ethynylzinc chloride or ethyl (tributylstannyl)propiolate, but the reactions were not generally applicable.

    Gold(I) can exhibit a cooperative effect with triphenylphosphine, accelerating the triphenylphosphine-mediated partial hydrogenation of activated alkynes. In this protocol, 3-arylpropiolates are selectively reduced to the Z-isomer when the aryl ring bears an electron-donor substituent, whereas 3-arylpropynones are reduced to the E-isomers.

    A synthesis of highly substituted alkenylphosphines by Lewis acid-mediated silylphosphination of substituted propiolates is described. The addition proceeded smoothly to give the corresponding acrylates, where the phosphino group attached at the β and the silyl group located at the α position of the resulting acrylate, in exclusively syn-stereochemistry.
