چکیده

A concise asymmetric synthesis of (+)-swainsonine (ent-1) is described starting from 2, which was readily prepared from commercially available l-glutamic acid. The method features installation of the indolizidine ring via an intramolecular cyclisation of α-sulfinyl carbanion as a key step. (+)-Swainsonine was obtained in 11.8% overall yield in 10 steps.

Asymmetric synthesis of (-)-swainsonine

This paper describes a new synthesis of (-)-swainsonine via the ring-closing metathesis reaction of a substituted 3-allyl-4-vinyl-2-oxazolindinone and subsequent diastereoselective syn-dihydroxylation of the resulting pyrrolo[1,2-c]oxazol-3-one.

Application of furyl-stabilized sulfur ylides to a concise synthesis of 8a-epi-swainsonine.

The total synthesis of 8a-epi-swainsonine has been achieved in 20% overall yield from R-glyceraldehyde dimethylacetonide 3 through epoxidation with the achiral furyl-substituted sulfonium ylide 2d as one of the key steps.

Asymmetric synthesis of anti-1,2-amino alcohols via the Borono-Mannich reaction: a formal synthesis of (-)-swainsonine.

Chiral alpha-hydroxy aldehydes generated in situ by the ADH reaction of vinyl sulfones undergo a borono-Mannich reaction with beta-styrenyl boronic acid and primary amines to give anti-1,2-amino alcohols in high enantiomeric purities (83-95% ee). This new method allows much more rapid access to these valuable chiral building blocks that has been used in a short formal synthesis (10 synthetic st...

Effect of swainsonine on the processing and turnover of lysosomal beta-galactosidase and beta-glucuronidase from mouse peritoneal macrophages.

The effect of swainsonine, an inhibitor of Golgi alpha-mannosidase II and lysosomal alpha-mannosidase, on the synthesis, processing, and turnover of two glycoproteins, lysosomal beta-galactosidase and lysosomal beta-glucuronidase, has been studied in cultured mouse peritoneal macrophages. No effect of the inhibitor on the relative rates of synthesis of the precursor form of either enzyme was ob...

Epimerization of C5 of an N-hydroxypyrrolidine in the synthesis of swainsonine related iminosugars.

Epimerization of C5 of an N-hydroxypyrrolidine ring by regioselective oxidation to a nitrone followed by diastereoselective reduction provides a new approach to the synthesis of swainsonine and related compounds. The only protection in the synthesis of the potent mannosidase inhibitor DIM (1,4-dideoxy-1,4-imino-d-mannitol) was the acetonation of d-mannose.
