A series of novel types of 7-(4,6-dimethoxypyrimidin-2-yl)oxy- and -thio-3-methyl-1 (3H)-isobenzofuranones were discovered at Dr R Maag AG. From the thio-isobenzofuranyl series, CGA 279 233--BSI-proposed common name pyriftalid--was chosen for further development as a grass herbicide for use in rice. General synthetic approaches to these new phthalic acid-derived compounds are given, with emphasis on
R R Maag AG博士发现了一系列新型的7-(4,6-二甲氧基嘧啶-2-基)氧基-和-硫代-3-甲基-1(3H)-异苯并呋喃酮。从硫代-异苯并呋喃基系列中,选择CGA 279 233(BSI提出的通用名称pyrpidalid)作为水稻中的除草剂进行进一步开发。给出了这些新的邻苯二甲酸衍生化合物的一般合成方法,重点是吡苯哌啶的合成及其理化行为。
