Abstract
##STR1## Novel piperidin-4-spiro-oxiranes of formula (I) are provided which have application in the synthesis of various anilidopiperidine compounds. The novel compounds can be synthesised in a one pot reaction from 4-substituted piperidones and phenylsulphoxide or sulphone starting materials. Use of the novel compounds allows anilidopiperidines to be produced in a significantly reduced number of stages than with previously known methods.
