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.

1-Methyl-3-(1,1,3-trioxo-1,3-dihydro-1λ$^6$-benzo[d]isothiazol-2-ylmethyl)-imidazolidine-2,4,5-triones 5a, 1-ethy1-3-(1,1,3-trioxo-1,3-dihydro-lλ$^6$/-benzo[d]isothiazol-2-ylmethyl)-imidazolidine-2,4,5-triones 5b 1-phenyl-3-(1,1,3-trioxo-1,3-dihydro-1λ$^6$-benzo [d]isothiazol-2-ylmethyl)-imidazolidine-2,4,5-triones 5c were obtained by means of 4 reaction steps involved the reaction of 1-methyl-urea and oxalyl chloride. Biological tests(Plant Response Screening Result, Insect Primary Screening Result and Fungicide Primary Screening Result) of synthesized sacccarin derivatives were executed.
