    摘要: A novel platinum (II) complex represented by the following formula (A): ##STR1## wherein R.sub.1 represents C.sub.1 -C.sub.5 lower hydrocarbon group, R.sub.2 and R.sub.3 represents hydrogen atom or C.sub.1 -C.sub.3 lower hydrocarbon group, the configuration of 1,2-diaminocyclohexane being cis, trans-l- or trans-d-. Since the platinum (II) complex has a strong anti-tumor activity and its toxicity is low, it is useful as an agent for treating malignant tumor.

    摘要: 2-(.omega.-alkoxycarbonyl alkanoyl)-4-butanolide can be produced unexpectedly with a high selectivity and yield through condensation reaction of .gamma.-butyrolactone with a highly available, lo.omega.-price dicarboxylate as represented by the following general formula: ROOC(CH2)nCOOR (where n denotes an integer of 7-13, and R denotes an alkyl group or an alkenyl group). Furthermore, a long-chain .omega.-hydroxycarboxylic acid can be produced by subjecting 2-(.omega.-alkoxycarbonyl alkanoyl)-4-butanolide to hydrolysis and decarboxylation and reducing the carbonyl groups in the resultant product into methylene groups.
