## Abstract A novel reaction of acylium and thioacylium ions, polar [4 + 2^+^] Diels–Alder cycloaddition with 1,3‐dienes and __O__‐heterodienes, has been systematically investigated in the gas phase (Eberlin MN, Cooks RG. __J. Am. Chem. Soc.__ 1993; 115: 9226). This polar cycloaddition, yet without

Under the influence of aluminum chloride the B-ethylthionitroolefin results in the formation of the thienium cation, which reacts with a variety of 1,3-dienes in the Diels-Alder sense. The cleavage of the resulting ring provides in one pot the 1,4-functionalized olefins in regio-and stereoselective
