摘要：

12H-Dibenzo[d,g] [1,3]dioxocin-6-carboxylic ester such as compound (Ⅰ) is a patented herbicide (US 4938790) with good pre- and postemergence activity on dicot weeds and sedges. Structure activity studies were initiated with the goal of discovering more synthetically accessible analogs with improved unit activity and crop-weed selectivity. As a part of above project the following novel compound (Ⅱ) was prepared to study the relationship between the structure and herbicidal activity:
