Their stru
ctures were
confirmed by IR,
1H NMR, mass spe
ctros
copy, and elemental analyses. The results of preliminary bioassays show that some of the title
compounds exhibit moderate to good herbi
cidal and fungi
cidal a
ctivities. For example, the title
compounds

ces:#jhet2563-eo-0007">,
ces:#jhet2563-eo-0010">,
ces:#jhet2563-eo-0012">,
ces:#jhet2563-eo-0013">, and
ces:#jhet2563-eo-0014"> possess 90–100% inhibition against the growth of roots of both rape and barnyard grass at 10 mg/L. Moreover, the title
compounds
ces:#jhet2563-eo-0010">,
ces:#jhet2563-eo-0011">, and
ces:#jhet2563-eo-0012"> possess 75–89% inhibition against
Botrytis cinerea at the
con
centration of 50 mg/L.
