method for the synthesis of a new series of R,R-2-(4-(2-(4-(5-chloro-3-halopyridin-2-yloxy)-phenoxy)-propionyloxy)-phenoxy)-propionic acid ester derivatives containing a halo-substituted pyridine carrying two R,R chiral centers from (R)-2-(4-hydroxyphenoxy)propionic acid, halopyridines and alcohols using base/cyanuric chloride/catalyst system is reported. Their herbicidal activities against grass weeds
合成新的R,R -2-(4-(2-(4-(5-氯-3-卤代吡啶-2-基氧基)-苯氧基)-丙酰氧基)-苯氧基)-丙酸系列的简便方法据报道,使用碱/氰尿酰氯/催化剂体系,含有由(R)-2-(4-羟基苯氧基)丙酸带有两个R 1,R 2手性中心的卤素取代的吡啶的酸酯衍生物,卤代吡啶和醇。评估了它们对草杂草的除草活性和农作物的选择性。
