  6-Deoxy-nojirimycin and 6-deoxy-gulo-nojirimycin in the racemic and d-series, d-fuco-nojirimycin and their 1-deoxyderivatives via hetero-Diels-Alder cycloadditions

  摘要：

  Nucleophilic ring opening of the cyclic sulfates (+/-)-9c and D-9c and of the epoxide (+/-)-13, or double substitution of the bis-triflate D-10 (derived from the Diels-Alder adduct of hexadienal dimethylacetal to achiral or enantiomerically pure nitroso-derivatives) led to 6-deoxy-nojirimycin and 6-deoxy-gulo-nojirimycin in the racemic and D-series, to D-fuco-nojirimycin and to their 1-deoxyderivatives via their crystalline 1-deoxy-1-sulfonic acid derivatives (sulfite adducts). 6-Deoxy-nojirimycin and its isomers are mixtures of alpha- and beta-anomers and of the corresponding imine.

  6-Deoxy-allo-nojirimycin in the racemic and d-series, 6-deoxy-d,l-talo-nojirimycin, their 1-deoxyderivatives and 6-deoxy-2-d,l-allosamine via hetero-Diels-Alder cycloadditions

  摘要：

  Diels-Alder cycloaddition of hexadienal dimethylacetal 3 to achiral acylnitroso-dienophile 5a gave the racemic cycloadducts 7a-c and, to chiral chloronitroso-dienophile 6, enantiomerically pure D-10a as sole adduct. Simple chemical transformations led to 6-deoxy-2-D,L-allosamine 15b, to 6-deoxy-D,L and D-allo-nojirimycin 15a, D-15a, to 6-deoxy-D,L-talo-nojirimycin 15c as well as to their l-deoxy-derivatives 16a, D-16a, 16c via their crystalline l-deoxy-l-sulfonic acid derivatives (sulfite adducts). Amino-sugars 16a,c are mixtures of alpha- and -beta-anomers and of the corresponding imines. (C) 1997 Elsevier Science Ltd.

  in-situ-generated acylnitroso dienophiles 5a and 5b, leading thereby to the corresponding dihydrooxazines 7a–d and 8c–d. cis-Glycolization of these latter adducts stereospecifically gave the dihydro derivatives 9a–d and 10d which, after sequential hydrogenolysis, deacetalization, and instant cyclization, led to the aminodeoxyribose derivatives 17a, 17f, and 18, and to the amino-dideoxyallose compounds 17c

• Potent glycosidase inhibitors via hetero Diels-Alder reactions: asymmetric synthesis of 5-methyl-trihydroxypyrrolidines
  作者：A. Defoin、Th. Sifferlen、J. Streith、I. Dosbaâ、M.-J. Foglietti

  DOI：10.1016/s0957-4166(97)00008-6

  日期：1997.2

  Some straightforward chemical transformations of oxazine diol 4, which was obtained from sorbaldehyde 2 by an asymmetric hetero Diels-Alder reaction followed by osmylation, led to the protected dihydroxypyrrolidine-aldehyde 8a and, after basic epimerisation, to 8b. Reduction of the aldehyde moiety and deprotection gave the potent glycosidase inhibitors 2,5,6-trideoxy-2,5-imino-D-altritol and D-allitol 9a and 9b. (C) 1997 Elsevier Science Ltd.

  Chemical transformations of chiral 1,2-oxazines 4, 5 gave the 2,5,6-trideoxy-2,5-imino D-alditols 12b, 13b in the D-altritol and D-talitol series, respectively. Basic aldehyde epimerisation led to the D-allitol isomer 15b. Compound 12b is a potent alpha-L-fucosidase and alpha-D-galactosidase inhibitor. (C) 2000 Elsevier Science Ltd. All rights reserved.
