    摘要: The invention describes an improved process for synthesizing 1-β-methyl-2-hydroxymethyl substituted carbapenems as key intermediates for the synthesis of anti-MRSA carbapenem antibiotics. The synthesis eliminates the use of BU3SnCH2OH and HMPA, which are toxic substances and not amenable to industrial scale production. The novel intermediates are also within the scope of this invention.

    摘要: 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.
