Abstract

Abstract: S, N-ketene acetal compounds with cyano, ester or dicyano containing pyridine methylene were synthesized, when R¹ on the alkenyl bond is ester, the compound is cyanoacrylate with pyridine methylamino, which hasn' t been reported yet.The configura-tion of target compound 3k was determined as Eby X-ray diffraction.The bioassay showed that the compounds 3k, 31 exhibited a high herbicidal activity and good selectivity with different species.

Key words: Pyridine methylene, S,N-Ketene acetal, Cyanoacrylate
