Abstract (en)
[origin: WO9633189A1] The present invention is directed to a novel process for the preparation of a spiroindoline sulfonamides of formula (I), wherein L is hydrogen or an amino protecting group. These compounds are useful in the preparation of certain spiro compounds which have the ability to stimulate the release of natural or endogeneous growth hormone. The spiro compounds may be used to treat conditions which require the stimulation of growth hormone production or secretion such as in humans with a deficiency of natural growth hormone or in animals used for food or wool production where the stimulation of growth hormone will result in a larger, more productive animal.
