NEW MATERIAL:A thiazolidine-2-carboxylic acid derivative of formula I (R 1 is H or lower alkyl; R 2 is 2W4C alkyl; X is O or S; n is 0,1 or 2). n EXAMPLE: 2-Ethyl-3-(3,5-dichlorophenylcarbamoyl) thiazolidine-2-carboxylic acid methyl ester. n USE: Agricultural and horticultural fungicide. Remarkably effective to gray mold, sclerotinia rot, etc. of green vegetables. Controls two or more blights at the same time. n PROCESS: The compound of formula Ia is prepared by reacting an ester of formula II (wherein R 1 is lower alkyl and n is 0) with 3,5-dichlorophenyl isocyanate of formula III in an organic solvent such as benzene. n COPYRIGHT: (C)1980,JPO&Japio |
