  An acylnitroso cycloaddition approach to the synthesis of highly oxygenated indolizidine alkaloids

  摘要：

  A synthetic approach to the synthesis of highly oxygenated indolizidine alkaloids is described. A key feature of the approach is intramolecular [4 + 2] cycloaddition between an acylnitroso dienophile and a tethered diene moiety, followed by ring contraction of the 1,2-oxazine so formed to a pyrrolidine. The requisite intermediates were prepared in optically pure form froM L-glutamic acid.
