| titleOfInvention | PROCEDURE FOR THE PREPARATION OF 3 - (CARBAMOYLOXIMINO) - AZACICLOHEPTANONES. |
| abstract | Procedure for the preparation of 3- (carbamoiloximino) -azacicloheptanonas of the formula I: **(See formula)** in which A stands for a tetramethylene radical optionally substituted by lower alkyl with 1-4 carbon atoms, R1 means hydrogen or an alkyl, alkenyl radical or a cycloalkyl radical optionally substituted by alkyl with up to 20 carbon atoms, R2 means an alkyl or alkenyl radical or a cycloalkyl radical optionally substituted by alkyl, with up to 20 carbon atoms or an aryl or aralkyl radical unsubstituted or substituted by halogen or lower alkyl, alkoxy or halogenoalkyl groups, with up to 4 carbon atoms, the symbols R1 and R2 signify together with the neighboring nitrogen atom a 3- to 10-membered heterocyclic radical, R3 means hydrogen or the group (see formula), where R4 and R5 are each hydrogen or lower alkyl radicals with up to 4 carbon atoms, cycloalkyl, aryl or aralkyl radicals, and X stands for oxygen or sulfur, characterized in that it is reacted in the presence of an acid binding agent, a hydroxy-imino-azacycloheptanone of formula II: **(See formula)** in which A has the significance indicated under formula I, with a carbamic acid halide of formula III: **(See formula)** or in the case that R3 means hydrogen, with two carbamic acid halides of formula IIIa: **(See formula)** in which Hal means chlorine or bromine, and X, R1, R2, R4 and R5 have the meanings indicated under formula I, or, in the presence of an acid binding agent, it is reacted with the forming components of the carbamic acid halide of formula III, namely phosgene or thiophosgene and an amine of formula IV: **(See formula)** in which R1 and R2 have the meanings indicated under formula I.
