Abstract

Enticed by metalation with a {CpRu^II} fragment, N-benzyl and N-phenethyl acrylamides participate in phosphine-promoted spirocyclizations even though they are normally unreactive in Morita-Baylis-Hillman (MBH)-type transformations. A ruthenium-arene cation serves as the electrophilic reaction partner for an in situ generated enolate ion in this organometallic variation of the MBH reaction. (Chemical Equation Presented).
