Synthesis and Herbicidal Activities of α-Isocyanocycloalkylideneacetamides¹⁾

Abstract

Various α-isocyanocycloalkylideneacetamides were synthesized by the reaction of isocyanoacetamides with ketones and following by dehydration. These compounds were examined for their inhibitory activity against the germination of rice, cucumber and radish seeds, and for their herbicidal effects on rice, tomato and weed seedlings. Among them, α-isocyanocyclohexylideneacetylpiperidine showed selective herbicidal activity against the broad-leaf plants.
