, (2018/07/30)
The invention provides a preparation method and an intermediate of pinoxaden. The preparation method includes: using 2-methylacrolein as a raw material; subjecting the raw material to cyclization andaromatization to obtain herbicide-pinoxaden. Compared with the prior art, the preparation method has the distinguishing features and the advantages that a completely different preparation strategy isadopted; a completely different nonaromatic compound is used as the raw material which is safe and easy to obtain; the preparation method is few in three wastes, low in cost and conducive to industrial production.

experimental part, p. 4241 - 4256 (2009/10/02)
Derivatives of the new class of 3-hydroxy-4-phenyl-5-oxo-pyrazolines were optimized towards both herbicidal activity on key annual grass weed species and selectivity in small grain cereal crops. The generic structure can be separated into three parts for the analysis of the structure-activity relationships, namely the aryl, the dione with its prodrug forms and the hydrazine moiety. Each area appears to play distinct and different roles in overall expression of biological performance which is further beneficially influenced by adjuvant response and safener action. Pinoxaden 6, a novel graminicide for use in wheat and barley incorporating a [1,4,5]oxadiazepane ring, eventually emerged as a development candidate from the discovery and optimization process.
