Synthesis and Herbicidal Activity of Opened Hydantoin-ring Derivatives of Hydantocidin.
We synthesized three hydantocidin derivatives and evaluated their herbicidal activity in order to elucidate the role of the spirohydantoin system at the anomeric center of hydantocidin. With application to foliage at 1000 ppm, only α-ureidoamide 14 demonstrated activity, the remaining compounds being found to be inactive.
