Zusammenfassung:The invention discloses 3-vinyl substituted urea derivatives, the structure of which is shown as the formula (I). The invention further discloses a preparation method for the 3-vinyl substituted urea derivatives. The preparation method comprises the step of synthesizing 3-vinyl substituted urea derivatives by adopting enaminone compounds and substituted formamide as active ingredients and cuprate as a catalyst at room temperature under nitrogen protection in the presence of an oxidant. The 3-vinyl substituted urea derivatives and the preparation method thereof are simple in reaction conditions, good in universality and short in reaction time.
