Abstract
NEW MATERIAL:An 1,3-oxazino (5,6-C) rifamycin derivative of formula I: (R is ≥7C alkyl, cycloalkyl, or hydroxyalkyl group).
EXAMPLE: N-n-Octyl-1,3-oxazino (5,6-C) Rifamycin.
USE: Effective antibiotics and useful as an intermediate for preparation of 3-iminomethyl derivative of Rifamycin SV, particularly Rifampicin.
PROCESS: 3-Formylrifamycin SV of formula II is reacted with formaldehyde and a primary amine of formula III in an inert organic solvent at room temperature to the boiling point of the solvent for 0.5W10 hr to give the objective substance of formula I.
