| titleOfInvention | Method for separation cis-3-amino-4-[2-2-phuryl-et-1-yl]-1-methyxycarbonylmethyl-azetidine-2-on into its enantiomers |
| abstract | Usage: in medicine for the synthesis of a medicament. SUMMARY OF THE INVENTION: Separation of the cis-3-amino-4- 2- (2-furyl) et-1-and 3-1-methoxycarbonylmethyl-azetidine-2-one racemate into cis-a, a-and cis -D / -enantiomers by contacting in the medium a polar organic solvent (heptane and / or isopropanol) with 0.5 molar equivalents of (-) hydrate - 2,3-4,6-di-b-isoprr - Pilidene-2-keto-and-gulonic acid, followed by separation of the precipitate co. whether the a, a isomer and the isolation of the salt of the /, / isomer from the solution. The degree of separation of isomers to 99.8%. 3 s, p. f-ly, 1 tab., / gh n "" o |
