A Facile Synthesis of Propellanes via Dianion Chemistry

摘要

A dianion-mediated dialkylation reaction provides a variety of propellanes. 12-Thia[4.4.3] propel-3-ene, 3-(N-benzyl)-2,4-dioxotricyclo[3.3.3.0] decane and 3-(N-benzyl)-2,4-dioxotricyclo[3.3.3.0] nonane were prepared by this dianion ring annulation methodology.
