Abstract
In connection with a total synthetic study we prepared 2-carbomethoxy-2-phenylselenocyclohexanone (2)2 and attempted to alkylate the ketone at the 6-position. However, to our surprise, base-promoted enolization with lithium diisopropyl amide (LDA) led to some rearrangement to the lithium enolate of 2-carbomethoxy-6-phenyl-selenocyclohexanone (3).
