Abstract

We investigated the synthesis and herbicidal activity of 23 toxoflavin analogs, 1a-w, in which aromatic rings (R) were introduced into the C-3 position. In paddy field conditions, 1k (R=2-CF3-C6H4) and 1w (R=2-thienyl) showed excellent herbicidal activity. Under upland field conditions, we found that toxoflavin analogs 1a (R=C6H5), 1n (R=2-CH3O-C6H4), and 1p (R=4-CH3O-C6H4) exhibited wide herbicidal spectrum against Echinochloa crus-galli (L) var. crus-galli (ECHCG), Chenopodium album, and Amaranthus viridis (AMAVI). The analog with the 2-fluoro group on benzene ring 1b also showed high herbicidal activity against both ECHCG and AMAVI.

3-取代弓形黄素类似物的合成及其除草活性。
研究了在C-3位上引入芳香环(R)的23种弓黄素类似物1a-w的合成及其除草活性。在水田条件下,1k (R=2-CF3-C6H4)和1w (R=2-噻吩基)表现出优异的除草活性。在旱地条件下,我们发现弓形黄素类似物1a (R=C6H5)、1n (R=2- ch30 - c6h4)和1p (R=4- ch30 - c6h4)对紫锥藻(Echinochloa cross -galli, L)、cross -galli (ECHCG)、Chenopodium album和Amaranthus viridis (AMAVI)具有较宽的除草光谱。苯环1b上含2-氟基团的类似物对eccg和AMAVI均有较高的除草活性。
