    Stereochemical Aspects of the Beckman Rearrangement of Oximes of Levoglucosenone and Its Dihydro Derivative. Enantioselective Synthesis of (+)- -Pelargonolactone
    摘要:
    Regiospecific C-5-halogenation with retention of configuration occurred upon Beckman fragmentation of levoglucosenone oxime using SOCl2 or PBr3. On the other hand, the oxime of its dihydro derivative gave under these conditions the C-6- substitution product. A stereoselective synthetic scheme for (+)-gamma-pelargonolactone, an attractant for the rice and corn weevils Sitophiltus zeamais, was developed from the fragmentation product of levoglucosenone oxime.

    Optically active γ-valerolactone and γ-nonanolactone have been synthesized via optical resolution using a newly developed chiral amine derived from L-phenylalanine. Both racemic γ-lactones were transformed to corresponding diastereomeric amides by amidation with the optical resolution agent. Fractional crystallization of diastereomeric amides, recrystallization of each diastereomer, and subsequent

    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.

    In the current study, we present a green toolbox to produce ecological compounds like lactone moiety. Rhodococcus erythropolis DSM 44534 cells have been used to oxidize both decane‐1,4‐diol (2a) and decane‐1,5‐diol (3a) into the corresponding γ‐ (2b) and δ‐decalactones (3b) with yield of 80% and enantiomeric excess (ee) = 75% and ee = 90%, respectively.

    The first synthesis of auxofuran, a newly discovered auxin-like signaling molecule of streptomycetes, has been achieved in seven steps and 59% overall yield from commercial starting materials. Central to the synthetic route is a click–unclick Diels–Alder cycloaddition/cycloreversion regimen enabling rapid access to an advanced intermediate from an unactivated alkyne.
