  Diastereoselective syntheses of 1-deoxyhomonojirimycin and two new 1,5,6-trideoxy-1,5-iminoheptitols with d-allo- and l-talo-configuration

  摘要：

  The synthesis of 1-deoxyhomonojirimycin 2, as well as two new diastereomers, namely 1,5,6-trideoxy-1,5-imino-D-allo-heptitol 3 and 1,5,6-trideoxy-1,5-imino-L-talo-heptitol 4, is described. Compound 2 was obtained from 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose-while 3 and 4 were obtained from 1, 2:5,6-di-O-isopropylidene-alpha-D-allofuranose. These compounds were transformed in a few steps to the corresponding beta-ketoesters 12 and 18, respectively, which were hydrogenated diastereoselectively in the presence of chiral ruthenium complexes with total control of the C-5 stereogenic centre. The resulting beta-hydroxyesters 13, 19a and 19b are key intermediates for the syntheses of the 1,5,6-trideoxy-1,5-iminoheptitols 2, 3 and 4, respectively. (c) 2006 Elsevier Ltd.
