Stereocontrolled transformation of nitrohexofuranoses into cyclopentylamines via 2-oxabicyclo[2.2.1]heptanes. III: synthesis of enantiopure methyl (1S,2S,3R,4S,5R)-2-amino-3,4,5-trihydroxycyclopentanecarboxylate
摘要:
The first total synthesis of enantiopure methyl (1S,2S,3R,4S,5R)-2-amino-3,4,5-trihydroxycyclopentanecarboxylate was carried out according to our recent novel strategy for the transformation of nitrohexofuranoses into cyclopentylamines, which is based on in intramolecular cyclization leading to 2-oxabicyclo[2.2.1] heptane derivatives. Differences in reactivity for this key step were rationalized by using molecular mechanism-based calculations. (C) 2008 Elsevier Ltd. All rights reserved.
Stereocontrolled Transformation of Nitrohexofuranoses into Cyclopentylamines via 2-Oxabicyclo[2.2.1]heptanes: Incorporation of Polyhydroxylated Carbocyclic β-Amino Acids into Peptides
摘要:
graphicA promising new strategy for the transformation of nitrohexofuranoses into cyclopentylamines, based on intramolecular cyclization followed by controlled opening of the resulting 2-oxabicyclo[2.2.1]heptane derivatives, allowed the first total synthesis of a carbocyclic beta-amino acid and its incorporation into peptides. This strategy also afforded a new route to cyclopentylamines with well-known glycosidase inhibition properties.
