A Single-Flask Synthesis of α-Alkylidene and α-Benzylidene Lactones from Ethoxyacetylene, Epoxides/Oxetanes, and Carbonyl Compounds
Low temperature treatment of (ethoxyethynyl)lithium with epoxides or oxetanes in the presence of BF(3)•OEt(2), followed by addition of aldehydes or ketones and warming to room temperature, affords structurally diverse five- and six-membered α-alkylidene and α-benzylidene lactones (5) in good to exce...
