MgX2-catalyzed annulation of methylenecyclopropanes with acyl cyanoalkenes was accomplished to give oxaspiro[2.5]octenes in excellent yields. The reaction proceeded through a rare intramolecular oxa-Michael addition of Mg enolate. The oxaspiro

The first organocatalytic asymmetric inverse-electron-demand Diels–Alder reaction of deconjugated enones by using a linear dienamine was explored. Electron-poor oxadienes having a cyano group were found to be suitable in this reaction. With a 20 mol-% loa
