摘　　要：A mild and highly efficient amine-catalyzed, IBX-mediated oxidation of aldehydes to （E） selective a, β-unsamrated aldehydes has been achieved in good yields. The process features a new oxidation of enamines to iminium ions in a catalytic fashion.A mild and highly efficient amine-catalyzed,IBX-mediated oxidation of aldehydes to(E) selective α,β-unsaturated aldehydes has been achieved in good yields.The process features a new oxidation of enamines to iminium ions in a catalytic fashion.
