Abstract
Abstract Secondary amines react with carbon dioxide and terminal alkynes in the presence of a catalytic amount of 4-1, 5-cyclooctadiene)(6-1, 3, 5-cyclooctatriene) ruthenium [Ru (COD)(COT)] and tertiary phosphine in toluene to give enol carbamates in good yields with high regio-and stereoselectivity. Cyclic enol carbamates, 5-methylene-2-oxazolidinones are obtained from N-substituted propargylamines and carbon dioxide in high yields.
