Intramolecular Cycloadditions of Mesionic Carbonyl Ylides with Alkynes. Synthesis of 5,6-Dihydro-4H-cyclopenta- and 4,5,6,7-Tetrahydrobenzofuran Derivatives

Intramolecular cycloaddition reactions of acetylenic isomuenchnones, formed in situ by rhodium acetate catalyzed decomposition of N-(diazoacetyl)-N-methylalkynamide derivatives 16a-c, 18c, and 18d have been studied.The intermediate cycloadducts fragmentate spontaneously under the reaction conditions (110 deg C) to afford the annulated furans 19a-c, 20c, and 20d. - Keywords: Carbonyl ylides; Furans; Intramolecular cycloadditions; Isomuenchnones
