Abstract

Saccharin derivatives were synthesized by means of 4 reaction steps involved the reaction of 1-methylurea (or 1-methylthiourea) and oxalyl chloride. 1-Alkyl(or phenyl)-3-(1,1,3-trioxo-1,3-dihydro-1$^{6}$ -benzo[d]isothiazol-2-ylmethyl)-imidazolidine-2,4,5-trione 5 and 1-alkyl(or phenyl)-2-thioxo- 3-(1,1,3-trioxo-1,3-dihydro-1$^{6}$ -benzo-[d]isothiazol-2-ylmethyl)-imidazolidine-4,5-dione 12 were obtained by means of 4 reaction steps involved the reaction of 1-methyl-urea(or 1-methylthiourea) and oxalyl chloride.

활성있는 새로운 농약을 창출하기 위해, saccharin 모체에 imidazolidine-2,4,5-trione과 2-thio-imidazolidine-4,5-dione 기를 도입시켰다. 각 saccharin 유도체들은 1-치환된 urea (혹은 1-치환된 thiourea)와 oxalyl chloride의 반응을 시작으로 4단계를 거쳐 합성하였다. 1-치환된 urea를 사용해서 1-치환된-3-(1,1,3-trioxo-1,3-dihydro-1$^{6}$-benzo[d]isothiazol-2- ylmethyl)-imidazolidine-2,4,5-trione 5a, 5b, 5c를 합성하였고, 1-치환된 thiourea를 사용하여 1-치환된-2-thioxo-3-(1,1,3-trioxo-1,3-dihydro-1$^{6}$-benzo[d]isothiazol-2-ylmethyl)-imidazolidine-4,5-dione 12a,12b, 12c를 합성하였다.
