Title: A method of manufacturing cylic 1-2-amino ketones
IPC: C07D211/72
Filed: 1934-02-13
Abstract: Compounds containing the group --COCH2--in a carbocyclic or heterocyclic ring are converted into their oximes, and the latter are treated with an aromatic sulphochloride to yield sulphonic esters of the oximes; the esters are subjected to alkaline saponification, and the saponification products is decomposed with an acid.  The effect of these reactions is to convert the --COCH2-- group into a --COCHNH2-- group. The hydroxyl group of the oxime may be in the sym- or anti-position to the adjacent methylene group.  In the examples: (1) a -hydrindone oxime is treated in pyridine with p-toluenesulphochloride, and the ester obtained is treated with a solution of potassium in alcohol; the precipitated potassium p-toluenesulphonate is filtered, and the filtrate is treated in ether with hydrochloric acid; b -amino-a -hydrindone hydrochloride is obtained, and may be converted into the picrate; (2) the oxime of 1 : 6 : 6-trimethyl-2-phenyl-4-oxopiperidine is subjected to the same series of reactions and yields the monohydrochloride of 1 : 6 : 6-trimethyl-2-phenyl-3-amino - 4 - oxopiperidine; (3) the oxime of 2 : 6 - diphenyl - 1 - methyl - 4 - oxopiperidine is treated in the same way to yield a hydrochloride of 2 : 6 - diphenyl - 1 - methyl - 3 - amino - 4 - oxopiperidine; (4) a  - ketotetrahydronaphthalene oxime similarly yields the hydrochloride of a  - keto - b  - aminotetrahydronaphthalene.  The Specification refers to a prior process in which the p-toluenesulphonic ester of a -ketotetrahydronaphthalene oxime is heated with alcohol under non-alkaline conditions and yields a g -(o-aminophenyl)butyric ester. 1 : 6 : 6 - Trimethyl-2-phenyl-4-oxopiperidine, used in example 2, is prepared by methylating with dimethyl sulphate the known compound 6 : 6 - dimethyl - 2 - phenyl - 4 - oxopiperidine.  Its oxime is prepared in the usual way.  2 : 6 - Diphenyl - 1 - methyl - 4 - oxopiperidine, used in example 3, is prepared from dibenzalacetone and methylamine, as described in German Specification 269,429.  Its oxime is prepared in the usual way.  The Specification as open to inspection under Sect. 91 states that the process may be applied to cyclic compounds containing the group --COCH2-- in a side chain, and includes examples in which (1) the p-toluenesulphonic ester of acetophenone oxime (syn-methyl form) yields the hydrochloride of w-aminoacetophenone; (2) the p-toluenesulphonic ester of propiophenone oxime yields the hydrochloride of a -aminopropiophenone.  It states that if the final step of the process is effected in the presence of alcohols, the acetals of the aminoketones are obtained.  It refers also to the condensation of two molecules of the aminoketones to yield dihydropyrazines, from which pyrazines are obtainable by oxidation. This subject-matter does not appear in the Specification as accepted.
