二苯并-1,3-二氧杂-环辛烷-2-羧酸丙酮肟酯(SYP-185)是沈阳化工研究院正在进行前期开发的除草剂。由二苯并-1,3-二氧杂-环辛烷-2-羧酸经两步反应制得,总收率70%。其结构经红外、核磁共振谱和元素分析确证。标题化合物在100 g a.i./hm2剂量下可防多种杂草;在300 g a.i./hm2对小麦安全。
Dibenzo-1, 3-dioxa-cyclooctane-2-carboxylic acid acetone oxime ester (SYP-185) is currently undergoing preliminary development of the Shenyang Chemical Industry Institute of herbicides. From dibenzo-1, 3-dioxa-cyclooctane-2-carboxylic acid obtained in two steps, the total yield of 70%. Its structure was confirmed by IR, NMR and elemental analysis. The title compounds are safe against a variety of weeds at a dose of 100 g a.i./hm2; safe for wheat at 300 g a.i./hm2.
