Abstract

Modeling and synthesis of novel hydroxyethyl 2-iminothiazolines were carried out through molecular modification of lead compound, 2-phenyliminothiazolines 1, for the purpose of development of new fungicidal agrochemicals. Oxygen atom of the hydroxyethyl group in 2-iminothiazolines 3 would locate in the proximity of the imino carbon at C-2 of 2-iminothiazoline moiety through neighboring group participation, and so that it would affect the biological activity of the molecule. Reaction of $\gamma$-chloroacetoacetanilides 5 with hydroxyethylureas 6 gave 29 kinds of new corresponding hydroxyethyl 2-iminothiazolines 3 in high yields.

신농약 살균제를 개발할 목적으로 선도화합물 2-페닐이미노티아졸린 유도체 1의 분자수정을 통하여 새로운 화합물 히드록시에틸 2-이미노티아졸런 유도체 3을 모델링하고 합성하였다. 2-이미노티아졸린 유도체 3의 히드록시에틸기의 산소 원자는 인접기 참여를 통하여 2-이미노티아졸린 골격의 2 위치의 이미노탄소에 접근이 가능하며 따라서 그들의 생물활성에 영향을 줄 것으로 예상되었다. 감마-클로로아세토아세트아닐리드 유도체 5와 히드록시에틸티오우레아 6을 반응시켜 29종의 히드록시에틸 2-이미노티아졸린 유도체 3을 높은 수율로 합성하였다.
