  Stereoselective Synthesis of (−)-Cytoxazone and (+)-5-Epi-cytoxazone

  摘要：

  A novel, stereo selective synthesis of (-)-cytoxazone la and stereo-selective synthesis of (+)-5-epi-cytoxazone 1b were achieved via stereoselective Grignard addition of vinylmagnesium bromide on N-Boc aldehyde obtained from p-hydroxy-D-phenylglycine 2 followed by cyclization of N-Boc alcohol 6, ozonolysis and reduction to get (+)-5-epi-cytoxazone. Compound 6 underwent mitsunobu conditions, deprotection of ester followed by cyclization of N-Boc alcohol to get (-)-cytoxazone.

  A new synthetic method for enantioselective synthesis of syn or anti -3-amino-3-aryl-1,2-alkanediols via proline catalyzed α-aminooxylation of β-amino aldehydes are described. This methodology is successfully applied to a concise and protecting group-free asymmetric synthesis of (–)-cytoxazone, (+)- epi -cytoxazone and formal synthesis of N-thiolated 2-oxazolidinone.

  The HKR of racemic syn- or anti- alkoxy- and azido epoxides catalyzed by Co(salen) complex affords a practical access to a series of enantioenriched syn- or anti- alkoxy- and azido epoxides and the corresponding 1,2-diols. This strategy has been successfully employed in the concise, enantioselective synthesis of bioactive molecules such as (S,S)-reboxetine and (+)-epi-cytoxazone.

  日期：2008.7

  The catalytic enantioselective synthesis of (+)-epi-cytoxazone has been accomplished in four steps from p-methoxybenzaldehyde N-Boc-imine with good diastereo- and enantioselectivity. This approach involves asymmetric Mannich reaction of an aldehyde with N-Boc-imine using the novel 2-pyrrole-derived imidazolidinone as an organocatalyst. (C) 2008 Elsevier Ltd. All rights reserved.

  Stereoselective synthesis of a potent cytokine modulator cytoxazone isomer has been achieved from 2,3-O-isopropylidene D-glyceraldehyde involving Grignard reaction, subsequent formation of an azide followed by reduction to the aminodiol, and finally cyclization of the N-Boc diol.
