  Organocatalytic syn-Aldol Reactions of Dioxanones with (S)-Isoserinal Hydrate: Synthesis of l-Deoxymannojirimycin and l-Deoxyidonojirimycin

  摘要：

  We report a new protocol for synthesis of L-1-deoxymannojirimycin, L-1-deoxyidonojirimycin, and the N-isopropyl derivative of the latter compound from the readily available precursors (S)-isoserinal hydrate and 2-tert-butyl-2-methyl-1,3-dioxan-5-one. The key steps include diastereoselective proline-catalyzed syn aldol transformation and a reductive amination/cyclization.

  The reaction of 2,3:4,5-diacetone-D-arabinose with protected dihydroxyacetone catalyzed by L-proline afforded two diastereoisomeric octoses in a 7:1 ratio in 75% yield. The anti (3S,4S) configuration at the newly created stereogenic centers was assigned to the main isomer on the basis of the X-ray analysis. The same reaction when catalyzed with unnatural D-proline provided the same products in a 1:20 ratio. (c) 2012 Elsevier Ltd. All rights reserved.
