Oxaziclomefone

Oxaziclomefone is a novel oxazinone herbicide that inhibits cell expansion in maize cell cultures without affecting turgor pressure or wall acidification. Oxaziclomefone is also used for pre- and early post-emergence barnyard grass control in rice.

ChEBI: Oxaziclomefone is an alkylbenzene.

Oxaziclomefone is commercially produced as a selective oxazinone herbicide, primarily for use in rice cultivation. Its synthesis involves the construction of a 1,3-oxazin-4-one ring substituted with phenyl, methyl, and 3,5-dichlorophenylpropyl groups. The process typically starts with the preparation of key intermediates such as 3,5-dichlorophenylpropionic acid derivatives, which are then cyclised with appropriate amines and ketones under controlled conditions to form the oxazinone core.

Blocks plant growth by inhibiting cell expansion in grass roots. Shows some residual activity.
