  • Copper-Catalysed Conjugate Addition of Grignard Reagents to 2-Methylcyclopentenone and Sequential Enolate Alkylation

    The copper/Rev‐JosiPhos‐catalysed asymmetric conjugate addition of Grignard reagents to 2‐methylcyclopentenone (1) provides 2,3‐disubstituted cyclopentanones in high yields and enantioselectivities, and good diastereoselectivities. Reaction of the in situ formed enolate with various alkylating reagents in the presence of 1,3‐dimethyltetrahydropyrimidine‐2(1H)‐one (DMPU) affords the corresponding products
    铜/ Rev-JosiPhos催化的格氏试剂到2-甲基环戊烯酮(1)的不对称共轭加成反应可高产率,对映选择性和良好的非对映选择性提供2,3-二取代的环戊酮。所述的反应在原位在1,3- dimethyltetrahydropyrimidine-2的存在下与各种烷基化试剂形成烯醇化物(1 ħ) -酮(DMPU),得到相应的产品中的一锅反应。此过程将创建两个邻近的立体中心,其中之一是四元的。

  • Oxonium ion-initiated pinacolic ring expansion reactions. Application to the enantioselective synthesis of the spirocyclic sesquiterpene ethers dactyloxene-B and -C
    作者:Marc D. Lord、Joanna T. Negri、Leo A. Paquette
    DOI:10.1021/jo00106a033
    日期:1995.1
    A convergent synthesis of dactyloxene-B (1) and -C (2) from a common optically active intermediate in seven steps has been achieved. Ozonolysis of(R)-(-)-linalool proceeded regioselectively to deliver a lactol, the benzoate of which when thermolyzed gave dihydrofuran 7. The second building block, levorotatory cyclopentanone 8, was produced by kinetically controlled lipase-induced hydrolysis of chloroacetate 15b. Saponification and oxidation of the less reactive ester was sufficient to provide (-)-8 whose condensation with the cerate of 7 gave rise to 19 and set the stage for implementation of the key structural rearrangement step. When stirred with Dowex resin, 19 was isomerized to four ketones. Following chromatographic separation, 20 and 21 were independently transformed into the target molecules via a two-step sequence. The spectral and optical properties of the two dactyloxenes compared very favorably with those reported earlier.
  • Enantioselective synthesis of natural (+)-dactyloxene-B and -C by actuation of oxonium ion-initiated pinacol rearrangement
    作者:Leo A. Paquette、Marc D. Lord、Joanna T. Negri
    DOI:10.1016/s0040-4039(00)73835-4
    日期:1993.9
    A direct route is described for assembling the spirocyclic framework of two sesquiterpene ethers derived biogenetically from the cyclization of farnesol with rearrangement of a methyl group.
