  • Carbonylative enantioselective meso-desymmetrization of cis-epoxides to trans-β-lactones: effect of salen-ligand electronic variation on enantioselectivity
    作者:Michael Mulzer、Jessica R. Lamb、Zachary Nelson、Geoffrey W. Coates
    DOI:10.1039/c4cc04397a
    日期:——
    Carbonylation catalysts for the desymmetrization of meso-epoxides yielding enantioenriched trans-β-lactones are reported. Fine-tuning the electronic properties of the ligand further improved enantioselectivity. The sterics of the substrate dictated whether a given electronic variation decreased or increased enantioenrichment, revealing an unexpected relationship between the substrate's steric environment and the electronic nature of the optimal catalyst.
    报道了用于降低小分子环氧化物对称性的碳基化催化剂,能够产生富含对映体的反式β-内酯。通过微调配体的电子特性进一步提高了对映选择性。底物的立体结构决定了特定的电子变化是减少还是增加对映富集,揭示了底物的立体环境与最佳催化剂的电子特性之间存在意想不到的关系。
  • Synthesis of β-Lactones by the Regioselective, Cobalt and Lewis Acid Catalyzed Carbonylation of Simple and Functionalized Epoxides
    作者:Jong Tae Lee、P. J. Thomas、Howard Alper
    DOI:10.1021/jo010295e
    日期:2001.8.1
    The PPNCo(CO)(4) and BF(3) x Et(2)O catalyzed carbonylation of simple and functionalized epoxides in DME gives the corresponding beta-lactones regioselectively in good to high yields. The carbonylation occurred selectively at the unsubstituted C-O bond of the epoxide ring, and this reaction tolerates various functional groups such as alkenyl, halide, hydroxy, and alkyl ether.
    在DME中PPNCo(CO)(4)和BF(3)x Et(2)O催化的简单和功能化环氧化物的羰基化反应以良好或高收率选择性地产生相应的β-内酯。羰基化选择性地发生在环氧环的未取代的CO键上,该反应可耐受各种官能团,例如烯基,卤化物,羟基和烷基醚。
  • Asymmetric synthesis of tetrahydrolipstatin and valilactone
    作者:Stephen C. Case-Green、Stephen G. Davies、Paul M. Roberts、Angela J. Russell、James E. Thomson
    DOI:10.1016/j.tetasy.2008.11.012
    日期:2008.11
    The highly diastereoselective aldol reaction between acyl complexes of the iron chiral auxiliary [(eta(5)-C5H5)Fe(CO)(PPh3)] and beta-hydroxy aldehydes (obtained via a Noyori asymmetric hydrogenation), followed by a tandem oxidative decomplexation-cyclisation process gives access to beta-substituted and alpha,beta-disubstituted beta-lactones in high ee. This methodology has been employed in the asymmetric syntheses of tetra hydrolipstatin and valilactone. (C) 2008 Elsevier Ltd. All rights reserved.
