    Abstract: A process for producing a 4-substituted azetidinone derivative represented by the following general formula [III]:

    (wherein OR is a protected hydroxy group, Y is an alkyl group, an alkoxy group, a silyloxy group, a carbamoyloxy group, an amino group, a substituted or unsubstituted aromatic group or a substituted or unsubstituted heterocyclic group, and n is an integer of 0 or 1, provided that n does not represent O when Y is an alkoxy group, silyloxy group, carbamoyloxy group or amino group), characterized in that a 2-azetidinone derivative represented by the following general formula [I]:

    (wherein OR is as defined above, and X is an alkyl group or a substituted or unsubstituted aromatic group) is reacted with thiocarboxylic acid represented by the following general formula [II]:
            HSCO-(CH₂) n -Y   [II]
    (wherein Y and n are respectively as defined above) in an organic solvent in the presence of copper compounds. The aforementioned method can shorten the production process compared with the prior method. It is also highly advantageous from an industrial point of view because it does not employ mercury salts.

    Abstract: In a process for oxidizing a feed comprising cyclohexylbenzene, the feed is contacted with oxygen and an oxidation catalyst in a plurality of reaction zones connected in series, the contacting being conducted under conditions being effective to oxidize part of the cyclohexylbenzene in the feed to cyclohexylbenzene hydroperoxide in each reaction zone. At least one of the plurality of reaction zones has a reaction condition that is different from another of the plurality of reaction zones. The different reaction conditions may include one or more of (a) a progressively decreasing temperature and (b) a progressively increasing oxidation catalyst concentration as the feed flows from one reaction zone to subsequent reaction zones in the series.

    Abstract: The present invention provides methods for making N-methylpyrrolidine and analogous compounds via hydrogenation. Novel catalysts for this process, and novel conditions/yields are also described. Other process improvements may include extraction and hydrolysis steps. Some preferred reactions take place in the aqueous phase. Starting materials for making N-methylpyrrolidine may include succinic acid, N-methylsuccinimide, and their analogs.
