PRACTICAL PROCEDURE FOR EPIMERIZATION OF 7α-AMINO-1-OXACEPHEMS TO 7β-AMINO EPIMERS
Aoki, T.,Haga, N.,Sendo, Y.,Konoike, T.,Yoshioka, M.,Nagata, W.
, p. 339 - 342 (2007/10/02)
7α-Amino-1-oxacephems can be epimerized to their 7β-amino epimers by treatment with chloral to give Schiff bases, followed by dehydrochlorination with Huenig base, borohydride reduction, and hydrolysis.
