A PROCESS FOR THE SYNTHESIS ANTHRANILIC DIAMIDE COMPOUNDS AND INTERMEDIATES THEREOF

The present invention disclosed a process for the synthesis of anthranilic diamide compound of formula (I), wherein, R1, R2, R3a, R3b, R3c, R4, R5, R6 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). 本发明公开了一种合成式(I)的氨茴二酰胺化合物的方法，其中，其中，R1、R2、R3a、R3b、R3c、R4、R5、R6和Z如具体实施方式中所定义。所述方法包括如下步骤：得到式(IV)的单氰基或二氰基取代的苯胺化合物，然后将其转化为式(V)的氨茴酸化合物或式(Va)的氨茴酰胺化合物。此外，式(VI)化合物可以任选地由式(IV或V或Va)化合物合成。
