In an attempt to discover novel fuse heterocyclic compound with high herbicidal activity, sixteen newly 2-alkythio-thieno[2,3-d]pyrimidin-4(3H)-ones have been designed and synthesized by the reaction of 3-propyl-6-ethylthieno[2,3-d]pyrimidine-2-thione with halo-hydrocarbon. Their structures were clearly verified by 1H NMR, IR, LC-MS and elemental analysis. Preliminary bioassay results indicate that some target compounds have excellent inhibitory activities on barnyard grass and rape. 2-Cyclopentylthio-3-n-propyl-6-ethylthieno[2,3-d]pyrimidin-4(3H)-one (4e) and 2-n-hexdecylthio-3-n-propyl-6-ethylthieno[2,3-d]pyrimidin-4(3H)-one (4o) show 100% inhibition rate to barnyard grass at the concentration of 100 mg/L.

Key words: thieno[2,3-d]pyrimidin-4(3H)-ones, synthesis, herbicidal activitiess
