A cationic Pd(II)-catalyzed reductivecyclization of alkyne-tethered ketones or aldehydes usingethanol as hydrogensource under mild conditions was developed. The reaction is an environmentally benign synthetic method and proceeds efficiently to give useful N-heterocycles or carbocycles bearing an exocyclic double bond and a hydroxyl group in high yield.
