I exhibited good herbicidalactivities; for example, the activities of compounds Ib, Ic, Ig, Ii, Ik, and Im were as good as the positive control herbicides (acetochlor, atrazine, mesotrione, and glyphosate). However, their structural isomers II and III and analogues IV did not display any herbicidalactivities in vivo, although some of them possessed selective inhibitory activity against Arabidopsis
为了找到具有新颖除草作用方式的新型高活性和低毒性除草剂先导化合物,由路易斯酸设计并合成了一系列含有嘧啶基部分I,II,III和IV的新型α-氨基膦酸酯衍生物(高氯酸镁)催化的醛,胺和亚磷酸酯的曼尼希型反应。通过光谱数据(IR,1 H NMR,31 P NMR,EI-MS)和元素分析清楚地鉴定了它们的结构。生物测定[体外,体内(GH1和GH2)]表明,大多数化合物I表现出良好的除草活性。例如,化合物Ib,Ic的活性,Ig,Ii,Ik和Im与阳性对照除草剂(乙草胺,阿特拉津,甲基磺草酮和草甘膦)一样好。然而,尽管它们中的一些具有体外对拟南芥的选择性抑制活性,但它们的结构异构体II和III和类似物IV在体内没有任何除草活性。有趣的是,发现化合物IVs,IVt和IVl对蚜虫或小菜蛾具有选择性的杀虫活性。, 分别。他们还初步研究了除草剂的作用方式和结构-活性关系。

homoallylic alcohols has been accomplished, which was catalyzed by a commercially available boronic acid. Due to the directing effect of the hydroxyl moiety, the ring opening reaction of a variety of 3,4-epoxy alcohols bearing different substitution patterns with various aromatic amines as nucleophiles proceeded in a stereospecific reaction pathway at the C-3 position furnishing various amino alcohols as products
