Abstract

Novel series of 5-benzyloxymethyl-3-(thiophen-5-yl)-1,2-isoxazoline derivatives were designed and synthesized, and their herbicidal activities to diverse weeds were tested under flooded paddy conditions in a greenhouse. Among them, some compounds (3d-f) showed good activities to dominant weeds such as Echinocloa orizycola and Monochoria vaginalis presl. at a rate of 0.063 kg/ha without the serious injury toward rice.

Thiophene에 다양한 치환기를 가진 5-benzyloxymethyl-1,2-isoxazoline 유도체들을 합성하였으며 이들의 제초활성을 온실의 논조건에서 시험하였다. 대부분의 화합물은 좋은 제초활성을 보였다. 특히 화합물 3d, 3e, 3f는 피, 물달개비 등에 대하여 0.063 kg/ha 정도의 약량에서도 강한 제초활성을 보이면서도 이앙벼에는 약해가 거의 나타나지 않는 선택성을 갖고 있었다.
