A method of preparing certain substituted alkali metal 4-carboxy-piperidine salts (I) by alkaline hydrolysis of certain novel substituted 1,3,8-triazaspiro[4.5]decane-2, 4-diones (IV) which in turn are obtained from certain novel substituted chlorosulphonylamido piperidines (III).
一种制备某些取代的碱金属4-羧基哌啶盐(I)的方法,是通过碱性水解某些新型取代的1,3,8-三氮杂螺[4.5]癸烷-2,4-二酮(IV)来获得,而这些化合物则来源于某些新型取代的氯磺酰胺基哌啶(III)。
