摘要：
The present invention relates to processes for the preparation of substituted cycloserine compounds of formula (I) wherein R1 is C1-C8alkyl, C1-C8haloalkyl, C3-C6cycloalkyl, aryl or aryl substituted by one to five R11, or aryl-C1-C4alkylene or aryl-C1-C4alkylene substituted by one to five R11； and each R11 is independently C1-C4alkyl, C1-C4haloalkyl, C1-C4alkoxy, C1-C4haloalkoxy, cyano or halogen； The invention also relates to intermediates produced by the processes. Compounds of formula (I) are useful intermediates for the production of compounds in the agricultural and pharmaceutical fields.
