    A total synthesis of the natural enantiomer of integerrimine (1), a twelve-membered dilactonic pyrrolizidine alkaloid of retronecine type has been achieved through the enantioselective synthesis and regioselective coupling of (+)-retronecine (4) and (+)-integerrinecic acid (methylthio)methyl ether (6).

  • Stereocontrol in Horner-Wadsworth-Emmons condensations of .alpha.-phosphono lactones with aldehydes: a synthesis of integerrinecic acid and senecic acid lactones
    作者:Koo Lee、John A. Jackson、David F. Wiemer
    DOI:10.1021/jo00074a023
    日期:1993.10
    The Homer-Wadsworth-Emmons condensations of alpha-phosphono lactones were investigated under a variety of conditions. Upon treatment with KHMDS and 18-crown-6 in THF, condensations of the five-membered ring phosphono lactones 7a and 8 with propionaldehyde afforded the E olefins cleanly. In contrast, these phosphonates gave predominantly the Z olefins upon treatment with propionaldehyde, K2CO3, and 18-crown-6 in THF. A similar, though somewhat less-pronounced trend was observed with the six-membered ring phosphono lactone 9a. However, in its condensation with acetaldehyde the more functionalized phosphono lactone 4 gave the best E selectivity (ca. 9:1) when DBU/CH3CN was used, providing the methyl ester of integerrinecic acid lactone (5) in 77% isolated yield. When K2CO3/18-crown-6/toluene was employed in a parallel reaction, only slight selectivity for the Z isomer was observed, but the methyl ester of senecic acid lactone (6) still was obtained in 43-46% yield from the product mixture.
