초록
2-(4-(6-chloro-2-benzoxazolyloxy)phenoxy)-N-phenylpropionamide 유도체들의 선택적 제초활성에 관한 연구(성 등, 1999)에 근거하여 수답에서 발아 전(pre-emergence), 벼 (Oryza sativa L.)와 피 (Echinochloa crus-galli)에 대한 제초활성에 미치는 구조-활성과의 관계 (SAR)를 Free-Wilson 방법과 Hansch 방법을 이용하여 정량적으로 검토하였다. SAR 분석결과, 피에 대한 제초활성은 N-phenyl 고리상 meta-치환된 1 치환체와 ortho, para-치환된 2 치환체로서 소수성의 적정값,
A new fourty six 2-(4-(6-chloro-2-benzoxazolyloxy)phenoxy)-N-phenylpro- pionamide derivatives were synthesized and the herbicidal activities against rice plant and barnyard grass with pre-emergence in down land were measured. The structure activity relationships (SAR) between the activities and physicochemical parameters of the substituted(X) N-phenyl group in substrates were analyzed and discussed by Free- Wilson and Hansch method from the basis on the former study (Sung. et. al., 1999). The conditions of selective herbicide activity both the barnyard grass and rice plant are shown that the optimal hydrophobicity,
