The effects of 2-phthalimidooxyalkanoic acid derivatives on the germination and root-growth of cress were examined. Since 2-phthalimidooxypropionates were most effective, the optically active ethyl esters were prepared. As the result of biological testing, the (S)-(-)-isomer exhibited stronger activity than the (R)-(+)-isomer. This result is contrary to those from commercial herbicides with similar structures, phenoxy- and oxyphenoxy-propionate-type compounds, where the (R)-isomers are generally known to be the active principles.
研究了2-邻苯二甲酰亚胺氧基烷酸衍生物对水芹萌发和根生长的影响。由于2-邻苯二甲酰亚胺氧基丙酸酯最为有效,因此制备了光学活性的乙酯。生物测试结果显示,(S)-(-)-异构体比(R)-(+)-异构体表现出更强的活性。这一结果与结构类似、属于苯氧基和羟苯氧基丙酸酯类商业除草剂的情况相反,后者通常认为(R)-异构体是活性成分。
