  Construction of Tetrahydrofuran-3-ones from Readily Available Organochalcogen Precursors via Radical Carbonylation/Reductive Cyclization

  摘要：

  [GRAPHICS]b-Hydroxyalkyl aryl chalcogenides, readily available by regioselective ring-opening of epoxides with nucleophilic benzeneselenolate or tellurolate, were O-alkylated by treatment with ethyl propiolate or (E)-1,2-bis(phenylsulfonyl)ethylene. Subsequent carbonylation/reductive cyclization in the presence of AIBN/TTMSS and carbon monoxide (80 atm) afforded tetrahydrofuran-3-ones in moderate to good yields.

  beta-Hydroxyalkyl aryl chalcogenides obtained by regioselective ring-opening of epoxides with benzeneselenolate or -tellurolate were found to undergo efficient hetero-Michael addition when treated with ethyl propiolate. Subsequent carbonylation/reductive cyclization of the resulting vinylogous carbonates in the presence of AIBN/TTMSS and carbon monoxide (80 atm) afforded 2,5-disubstituted tetrahydrofuran-3-ones, predominantly as cis isomers (cis/trans = 4/1-9/1). Starting from a polymer-supported diaryl diselenide, the methodology was also successfully extended to solid-phase synthesis. Vinylogous carbamates prepared by hetero-Michael addition of aziridines to electron-deficient alkynes were regioselectively ring-opened with benzeneselenolate from the sterically least hindered side. Radical carbonylation/reductive cyclization of the resulting N-vinyl-beta-amino-alkyl phenyl selenides afforded 2,5-disubstituted pyrrolidin-3-ones, predominantly as cis isomers (cis/trans = 3/1-12/1).
