- Synthesis of d -Fagomine and Its Seven- and Eight-Membered Higher-Ring Analogues, and the Formal Synthesis of (+)-Australine from l -Xylose-Derived Chiron
-
The synthesis of d-fagomine and its seven- and eight-membered higher-ring analogues from commercially available l-xylose is reported. The syntheses involve elaboration of a common alkenol precursor obtained from l-xylose-derived hemiacetal. The key steps

- Synthesis of 6-deoxy-homoDMDP and its C(5)-epimer: Absolute stereochemistry of natural products from Hyacinthus orientalis
-
A concise enantioselective synthesis of 2,5-imino-2,5,6-trideoxy-D-manno-heptitol (6-deoxy-homoDMDP) and 2,5-imino-2,5,6-trideoxy-L-gulo-heptitol has been achieved. These compounds were used as stereochemical references to establish the absolute configuration of the corresponding naturally occurring stereoisomers, recently isolated from Hyacinthus orientalis.

- A facile and rapid route to a new series of pyrrolizidines structurally related to (+)-alexine and (+)-australine
-
Addition of allylmagnesium chloride to protected L-xylofuranosylamine gave, after intramolecular cyclization, the corresponding polyhydroxylated 2-allylpyrrolidines. New series of analogues of (+)-alexine and (+)-australine were readily obtained from these intermediates by dihydroxylation, intramolecular nucleophilic displacement and subsequent deprotection. The determination of the configuration at the newly formed stereocentres was based on NMR experiments. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
