| titleOfInvention | PROCEDURE FOR OBTAINING OXIMES OF 3-FORMIL-RIFA-MICINA SV. |
| abstract | Procedure for obtaining 3-formyl-rifamycin SV oximes of formula: **(See formula)** wherein R is selected from the group consisting of alkyl of at least 2 carbon atoms, alkenyl, alkynyl, cycloalkyl, alkoxyalkyl, cycloalkoxyalkyl, hydroxyalkyl, carboxyalkyl, carbalkoxy, carbamyl, cyanoalkyl, nitroalkyl, aryloxyalkyl, aralkoxyalkyl, heterocicloxialquilo, aminoalkyl, mono- and di-lower alkyl aminoalkyl, substituted benzyl, C2-C8 alkyl mono- and poly-aryl-substituted, lower alkyl substituted with 1 to 3 mono- or polynuclear heterocyclic rings containing at least one heteroatom selected from oxygen, nitrogen and sulfur, except morpholine rings; R1 is chosen from the group consisting of hydrogen and acetyl; and derivatives of said hydrogenated oximes at positions 16, 17, 18, 19, 28, 29; characterized in that it comprises contacting a compound selected from 3-formyl-rifamycin SV, 25-deacetyl-3-formylriphamicin SV and its hydrogenated derivatives at positions 16, 17, 18, 19, 28, 29, with an approximately equimolar amount of an O-substituted hydroxylamine of formula RONH2, wherein R is defined as above.
