    Stereochemistry of alkyl 3-substituted 4-halotetrahydro-2-oxo-3-furancarboxylates: 2—1H and13C NMR spectra
    摘要:
    AbstractThe 1H NMR parameters of methyl 3‐substituted cis‐4‐halotetrahydro‐2‐oxo‐3‐furancarboxylates are reported, with assignments of the ring protons based on solvent‐induced changes in the vicinal trans coupling constants, 3J(H‐4, H‐5). Preferred conformations, ce with a pseudo‐equatorial halogen for the cis isomers and ta with a pseudo‐axial halogen for the trans isomers, have been suggested on comparison of the magnitudes of J(trans) and J(gem) in both series. The 3J(13CH3, H‐4) values measured for methyl cis‐4‐bromotetrahydro‐3‐methyl‐3‐furancarboxylate, methyl trans‐4‐bromotetrahydro‐3‐methyl‐3‐furancarboxylate and trans‐3,4‐dibromodihydro‐3‐methyl‐2(3H)‐furanone have confirmed the stereochemical assignments.

    日期:2002.7
    A new method for the synthesis of γ-butanolides is described. The titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides, followed by acidic work-up, affords the corresponding butyrolactones in 44–83% yield.

  • Economical, Green, and Safe Route Towards Substituted Lactones by Anodic Generation of Oxycarbonyl Radicals
    作者:Alessia Petti、Matthew C. Leech、Anthony D. Garcia、Iain C. A. Goodall、Adrian P. Dobbs、Kevin Lam
    DOI:10.1002/anie.201909922
    日期:2019.11.4
    A new electrochemical methodology has been developed for the generation of oxycarbonyl radicals under mild and green conditions from readily available hemioxalate salts. Mono- and multi-functionalised γ-butyrolactones were synthesised through exo-cyclisation of these oxycarbonyl radicals with an alkene, followed by the sp3 -sp3 capture of the newly formed carbon-centred radical. The synthesis of functionalised
