| titleOfInvention | Process for the preparation of enantiomerically pure polyhydroxylated nitrogen heterocycles. |
| abstract | Process for the preparation of enantiomerically pure polyhydroxylated nitrogenous heterocycles of formula (I) and their enantiomers: (CF DRAWING IN BOPI) in which G1, R1, R2, R3 and n are as defined in the description, consisting of (a) to reacting an amine of formula: (CF DRAWING IN BOPI) on a bis-epoxide, enantiomerically pure and having a C2 axis of symmetry, of formula: (CF DRAWING IN BOPI) to obtain a mixture of the piperidin derivative and the azepanic derivative, (b) separating the piperidine derivative from the azepanic derivative, (c) optionally replacing the protective groups of the alcohol functions and / or the -alk (1C) -Ar residue representing the substituent R1 of the compounds obtained in (b) by atoms of ′ hydrogen. |
