  名称：

  A Five-Membered Enantiopure Cyclic Nitrone from Malic Acid by Regioselective Oxidation of Cyclic Hydroxylamine. Synthesis of (1S,7S,8aR)-Octahydro-1,7-dihydroxyindolizine

  摘要：

  The chiral optically pure five-membered 3-tert-butoxy-1-pyrroline N-oxide (1) was synthesized by a convenient five-step procedure from diethyl L-malate. The key step is the regioselective HgO dehydrogenation of the N-hydroxypyrrolidine 6 obtained by double-nucleophilic displacement of a (bis)mesylate with hydroxylamine. A rationalization of the observed regioselectivity of the oxidation by studying the oxidation of a deuterated N-hydroxypyrrolidine 20 is reported. Nitrone 1 has been applied to the synthesis of a new (1S,7S,8aR)-1,7-dihydroxyindolizidine (28) via 1,3-dipolar cycloaddition strategies.
