    Baker's yeast reduction of arylalkyl and arylalkenil γ- and δ-keto acids
    摘要:
    gamma- and delta-Lactones 5, 6, 13, 14, 15 and 16 were synthesized via baker's yeast reduction of the corresponding keto acids 3 ,4 and 9-12. The enantioselectivity of the reduction is strongly dependent on the nature of the keto acid: the delta-lactones were always obtained in an ee% higher than the gamma-lactones and ranging from 70% to 100%.

  • Biocatalytic oxidation of 1,4-diols and γ-lactols into γ-lactones: application to chemoenzymatic synthesis of drospirenone
    作者:Diego Romano、Martina Contente、Tiziana Granato、William Remelli、Paolo Zambelli、Francesco Molinari

    日期:2013.5
    4-butanediols with Acetobacter aceti MIM 2000/28 gave the corresponding γ-lactones in good yields. The biotransformation occurred with intermediate formation of γ-lactols, which are also substrates for oxidation with Acetobacter aceti MIM 2000/28, as validated by selective biotransformation of 6β,7β;15β,16β-dimethylene-3-oxo-17α-pregn-4-en-21,17-carbolactol to drospirenone.

    日期:2022.4.4
    A robust and efficient nickel–phosphine complex has been discovered for the asymmetric hydrogenation of aliphatic ketoacids. A proton promoted the activation of C=O bonds and controlled the stereoselectivity through hydrogen bonds to obtain the corresponding products in high yields with excellent enantioselectivities.
