Several different alkoxycarbonyl‐substituted 2‐benzoxazolinone moieties have been incorporated into a tetrahydroisoindoline‐1,3‐dione scaffold to provide 25 compounds (1a–1u and 2a–2d). The structures of these compounds were confirmed by 1H and 13C NMR, HRMS and X‐ray single‐crystal diffraction. Some of these compounds (1g, 1h, 1j, 1k) exhibited excellent herbicidal activities against Abutilon theophrasti
几个不同的烷氧基羰基取代的2-苯并恶唑啉酮基团已被掺入四氢异吲哚啉-1,3-二酮骨架中,以提供25种化合物(1a - 1u和2a - 2d)。这些化合物的结构通过1 H和13 C NMR,HRMS和X射线单晶衍射确定。这些化合物的一些(1克,1H,1J,1K)显示出优异的除草活性对苘麻,反枝苋和稗在375克活性成分的速率·公顷-1。其中,化合物1H和1J显示针对最好苗后除草效果苘麻与ED 50个的值1.8和5.3克活性成分·公顷-1,分别,这是优于市售的氟锁草醚(44.3克AI·哈-1)。田间试验表明,化合物1h具有与高浓度activity去津相似的除草活性,并且发现玉米比ize去津更安全。因此,这项研究的结果表明,化合物1h可用作玉米田出苗后的除草剂。
