    Oxone-promoted hydration of electron-deficient allenic esters and ketones into 1,3-dicarbonyl compounds
    摘要:
    A novel and mild protocol for the hydration of electron-deficient allenic esters and ketones into various 1,3-dicarbonyl compounds is described. The hydration of allenes promoted by oxone in DMF afforded the corresponding products in moderate to good yields. This work features the employment of only a catalytic amount of inexpensive and nontoxic solid reagent oxone (2KHSO(5)center dot KHSO4 center dot K2SO4), avoiding the utility of toxic metals or traditional Bronsted acids, in a green version of viewpoint. A possible reaction mechanism for this transformation is also primarily proposed. (C) 2015 Elsevier Ltd. All rights reserved.

  • Rhodium(III)-Catalyzed Annulation of Acetophenone <i>O</i>-Acetyl Oximes with Allenoates through Arene C–H Activation: An Access to Isoquinolines
    作者:Quannan Wang、Jiang Lou、Zilong Huang、Zhengkun Yu

    日期:2019.2.15
    Rhodium(III)-catalyzed annulation of acetophenone O-acetyl oximes with allenoates was achieved, affording isoquinolines in good to excellent yields with high regioselectivities under redox-neutral conditions. Allenoates acted as the C2 synthons in the annulation reaction. The present synthetic methodology features good functional group tolerance and avoids metal salts as the external oxidants. The

    An interesting remote δ-C 1,6-addition and an isomerization cascade reaction for phosphine-catalyzed activated alkynes have been disclosed. The products featuring a functional diene and a 1,1-diaryl methyl motif have been obtained in moderate to good yields (30–86%) by applying para-quinone methides (p-QMs) and δ-substituted alkynoate with tributylphosphine (PnBu3) catalysis, along with high regioselectivity

  • Allene Carboxylates as Dipolarophiles in Rh-Catalyzed Carbonyl Ylide Cycloadditions
    作者:Laxmidhar Rout、Andrew M. Harned
    DOI:10.1002/chem.200902208
    日期:2009.12.7
    Face‐to‐face: Allene carboxylates can serve as efficient dipolarophiles for Rh‐catalyzed carbonyl ylide cycloadditions (see scheme). The endo and exo products arise from cycloaddition on the same face of the allene, but opposite faces of the dipole. This facial selectivity results in the formation of two of the four possible diastereomers.

    developed for the novel functionalization of allenyl esters. First, new phosphazenes derived from trifluorodiazoethane and phosphines were generated and reacted with allenyl esters to give unexpected α‐iminophosphoranes through the creation of C=P, C=N, and C−H bonds at the α‐, β‐, and γ‐carbon atoms, respectively, of the allenyl esters. The α‐iminophosphoranes did not react with aldehydes in a classic Wittig
    开发了一种伸缩工艺,该工艺涉及将四种试剂(三氟重氮乙烷,膦,烯丙基酯和乙酸)连续添加到单个反应器中,以实现烯丙基酯的新型功能化。首先,生成了衍生自三氟重氮乙烷和膦的新磷腈并与烯丙基酯反应,通过在α-,β-和γ-上形成C = P,C = N和C-H键,产生了意想不到的α-亚氨基正膦烯丙基酯的碳原子。在经典的维蒂希反应中,α-亚氨基正膦不与醛反应,而是获得了β-烯氨基酯。反应的全部顺序提供了烯丙基酯的正式加氢肼化反应。该方法扩展到其他相关的重氮化合物,并用于制备新型5-吡唑啉酮衍生物。

    We have successfully developed a novel and efficient phosphine-catalyzed sequential [2+3] and [3+2] annulation reaction of gamma-substituent allenoates to construct bicyclic[3, 3, 0]octene derivatives. The protocol uses readily available gamma-substituent allenoates as the starting materials, inexpensive PBu3 as the catalyst, and the corresponding products were obtained in good to excellent yields
