Reactions of active methyne compounds with vinyl selenones. One-step synthesis of 2-acylcyclopropanecarbaldehydes
Abstract
The reactions of anionic species of 2-substituted 1,3-dicarbonyl compounds with vinyl selenones afford the corresponding 1,2-diacylcyclopropanes in good yields through conjugate and 1,2-addition reactions followed by rearrangement and substitution processes.
