Preparation of Aromatic β-Selenolactams and Their Bioactivities as Agricultural Chemicals

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the possibility of aromatic β-selenolactams being
used in agricultural chemicals. A series of β-selenolactams with aromatic substituents at the 1-,
2- and 3-positions were synthesized and their bioactivities were evaluated. Acarianicidal and
insecticidal activity against common destructive insects, antibacterial activity against seven
common plant pathogens, and plant growth activity of typical food crops were investigated. We
found that introduction of 4-chloro and 4-methyl groups on 2- or 3-phenyl groups of the β-selenolactam
ring brought about acarianicidal activity against adults and eggs of Plutella xylostella.
However, except for moderate to weak effect on fatality of Culex pipiens molestus
Forskal, insecticidal activity against two other kinds of insects, antibacterial activity against
plant pathogens, and activity on plant growth regulation were not detected among the β-selenolactam
derivatives.
