Summary: | A series of 3,4-dichloroisothiazole based novel strobilurin analogs were designed and synthesized, and their structures were elucidated by NMR and HRMS, and the typical crystal structure was determined by X-ray diffraction for validation. Results from different biological assays suggested that most target compounds displayed very good fungicidal activity against one or multiple plant pathogens
in vitro
and
in vivo
. Among them, compounds
6d
,
6g
and
8d
showed a broad spectrum of fungicidal activity. Further field experiments indicated that compound
8d
displayed better efficacy against
Sphaerotheca fuliginea
than commercial standards azoxystrobin and trifloxystrobin, and better efficacy against
Pseudoperonospora cubensis
than trifloxystrobin. Overall, a new fungicidal candidate for plant disease management was discovered in this study.
A series of 3,4-dichloroisothiazole based novel strobilurin analogs were synthesized, the compound
8d
was discovered as a new fungicidal candidate with better efficacy than commercial standards. |
