  Synthesis of a protected trihydroxyindolizidine 3-carboxylate via a hetero-Diels–Alder addition of ethyl 2-nitrosoacrylate to a d-ribose-derived exo-glycal

  摘要：

  A protected trihydroxyindolizidine 3-carboxylate was prepared by a 6-endo epoxide cleavage, which in turn was intermediately formed from the hetero-Diels-Alder adduct of ethyl 2-nitrosoacrylate to a D-ribose-derived exo-glycal. (C) 2010 Elsevier Ltd. All rights reserved.
