Abstract
NEW MATERIAL:The trans-isomer of the compound of formulaI(X is halogen or lower alkyl) and the threo-isomer of the compound of the formula II.
EXAMPLE: trans-5-(4-chlorophenyl)-4-methyl-2-thiazolidone and threo-2-amino-1- (4-methylphenyl)propylbenzyldithiol carbonate hydrochloride.
USE: Intermediate of pesticides and pharmaceuticals. Especially useful as an intermediate of the compound of formula IV having excellent miticidal activity.
PROCESS: The threo-isomer of the compound of formula II can be prepared, e.g. by reacting the erythro-isomer of the compound of formula III with benzyl chloride in the presence of an amine and CS2. The product can be converted to the trans-isomer of the compound of formula I by reacting with an alkali in an alcohol such as methanol.
