Abstract A facile, mild, and efficient methodology for the ionicDiels–Alderreaction of acetals of α,β‐unsaturated ketones and aldehydes as dienophiles with various 1,3‐dienes employing MgBr2 as the Lewis acid catalyst to furnish corresponding Diels–Alder adducts at ambient temperature is described.
