Regioselective intramolecular ring closure of 2-amino-6-bromo-2,6- dideoxyhexono-1,4-lactones to 5- or 6-membered iminuronic acid analogues: Synthesis of 1-deoxymannojirimycin and 2,5-dideoxy-2,5-imino-d-glucitol

1-Deoxymannojirimycin (8c) was synthesised from 2-amino-6-bromo-2,6- dideoxy-d-mannono-1,4-lactone (7) by intramolecular direct displacement of the C-6 bromine employing non-aqueous base treatment followed by reduction of the intermediate methyl ester. Li

We have synthesized 3-hydroxy- and 3,4,5-trihydroxypipecolic acid derivatives corresponding to 5-aza derivatives of uronic acids and evaluated their inhibitory activities against various glycosidases including β-glucuronidase. Compounds 4 and 5 were chosen as common intermediates for the synthesis of 3,4,5-trihydroxypipecolic acids and 3-hydroxypipecolic acids as well as for 3-hydroxybaikiain, a unique natural product isolated from a toxic mushroom. Cross aldol reaction of N-Boc-allylglycine derivative with acrolein followed by the ring-closing metathesis gave 4 and 5 as a mixture of diastereomers which could be separated by silica gel column chromatography. By employing lipase-catalyzed kinetic resolution, the synthesis of both l- and d-isomers of 3,4,5-trihydroxy- and 3-hydroxypipecolic acids was achieved. None of the compounds tested showed inhibitory activity against α- and β-glucosidases. On the other hand, l-23 and l-29 were found to have potent inhibitory activity against β-glucuronidase. In addition, it is interesting that some uronic-type azasugar derivatives showed moderate inhibitory activities against β-N-acetylglucosaminidase.

A short and efficient synthesis of (-)-deoxymannojirimycin and (2S,3R,4R,5R)-3,4,5-trihydroxypipecolic acid is described with D-glucono-δ-lactone as chiral educt.Key transformations included selective cleavage of a terminal isopropylidene group with Dowex 50W-X8 (H+) and intramolecular nucleophilic amination.

Deoxymannojirimycin may be prepared in moderate amounts in an overall yield of 35percent in ten steps from diacetone glucose; the key step is formation of the piperidine ring by intramolecular nucleophilic displacement of a triflate at C-2 of a methyl glucofuranoside by a nitrogen function at C-6, irrespective of the anomeric configuration of the sugar.A synthesis of (2S,3R,4R,5R)-3,4,5-trihydroxypipecolic acid is reported.

The value of methyl 3-O-benzyl-2,6-dideoxy-2,6-imino-α-D-mannofuranoside as a divergent intermediate for the preparation of polyhydroxylated piperidines is illustrated by the synthesis of deoxymannojirimycin (1,5-dideoxy-1,5-imino-D-mannitol), fagomine (1,5-imino-1,2,5-trideoxy-D-arabino-hexitol), deoxynojirimycin (1,5-dideoxy-1,5-imino-D-glucitol), 2-acetamido-1,5-imino-1,2,5-trideoxy-D-mannitol, 2-acetamido-1,5-imino-1,2,5-trideoxy-D-glucitol, 2S,3R,4R,5R-trihydroxypipecolic acid and 2S,3R,4R,5S-trihydroxypipecolic acid.
