Abstract
NEW MATERIAL:Optically active N-benzyl-acetamide derivatives of formula I (R1 is tertiary alkyl; R2 is halogen).
EXAMPLE: An amide from 1-α-methylbenzylamine and 1-α-bromo-tert-butylacetic acid.
USE: A herbicide: it is effective on annual plants and perennial plants such as Mizugayatsuri (Cyperus serotinus ROTTB), Urikawa (Arrowhead) or Hotaru-i (Bulrush) and can be applied to rice paddies, fields and orchards. It shows activity before the germination and during the growing periods of weeds, too and causes no injury to crops.
PREPARATION: The reaction of an acetic acid derviative of formula II or its reactive derivative with α-methylbenzylamine gives the compound of formula I. At least one of the starting materials is required to be optically active.
