摘要:The present invention disclosed a process for the synthesis of anthranilic diamide compound of formula (I), n n n n n n n n n n wherein, R 1 , R 2 , R 3a , R 3b , R 3c , R 4 , R 5 , R 6 and Z are as defined in the detailed description. The process comprising the step of obtaining a mono- or dicyano substituted aniline compound of formula (IV) which is then converted to an anthranilic acid compound of formula (V) or an anthranilic amide compound of formula (Va). Further, the compound of formula (VI) can be optionally synthesized from compound of formula (IV or V or Va)

权利人:ALBEMARLE CORP
摘要:Process for preparing metyrapone type compounds are generally described herein. In particular, one step process for preparing metyrapone type compounds are described herein. Such processes generally include an alpha-carbon arylation coupling reaction between 3-isobutyrylpyridine and 3-halopyridine compounds in the presence of a palladium catalyst and a phosphine ligand to form the metyrapone-type compounds.
