Ruthenium–carbenoid catalysts such as Grubbs’ complex I mediate efficiently the isomerization of β,γ-unsaturated ethers and amines to the corresponding vinyl ethers and enamines. This reaction can be useful in the deprotection of allyl and homoallyl ethers as well as amines.
complex in combination with quinaldic acid shows high reactivity and chemoselectivity for the catalytic deprotection of hydroxyl groups protected as allyl ethers. The catalyst operates in alcoholic solvents without the need for any additional nucleophiles, satisfying the practical requirements of operational simplicity, safety, and environmental friendliness. The wide applicability of this deprotection
