Preparation and Use of a New Propiolate Anion Equivalent: 1-Ethynyl-4-methyl-2,6,7-trioxabicyclo[2,2,2]octane
摘要:
1-(Lithioethynyl)-4-methyl-2,6,7-trioxabicyclo[2,2,2]octane (8) prepared from propiolic acid, is introduced as an easy to handle propiolate anion equivalent. Its condensation with different electrophiles is described.
