  Exploring the metal-catalyzed reaction of furans with alkyl α-diazomethanesulfonate and α-diazomethanephosphonate: synthesis of ω-acyl-substituted sulfono- and phosphonobutadienes

  摘要：

  The metal-catalyzed reactions of neopentyl or,-diazomethanesulfonate (DAMS) and diisopropyl alpha-diazomethanephosphonate (DIDAMP) with furan, 2-methylfuran and 2-methoxyfuran are reported. The products consist mostly of omega-acyl-substituted sulfono- or phosphonobutadienes and exo-cyclopropane derivatives. Treatment of the multicomponent reaction mixtures with iodine afforded exclusively the corresponding (E,E)-sulfono- and phosphono-omega-acylfunctionalized dienes, thus providing a short and efficient synthetic route to these hitherto unreported classes of compounds.
