| abstract |
The present invention relates to a process for the preparation of substituted cycloserine compounds of formula (I) Wherein R 1 is C 1 ‑C 8 alkyl, C 1 ‑C 8 haloalkyl, C 3 ‑C 6 cycloalkyl, aryl or aryl substituted by one to five R 11 , or aryl‑C 1 ‑ C 4 alkylene or aryl-C 1 -C 4 alkylene substituted by one to five R 11 ; and each R 11 is independently C 1 -C 4 alkyl, C 1 -C 4 haloalkyl, C 1 -C 4 alkoxy, C 1 -C 4 haloalkoxy, cyano or halogen; the invention also relates to intermediates resulting from these processes. Compounds of formula (I) are useful intermediates for the production of compounds in the fields of agriculture and medicine. |
