for the synthesis of 3,4-dihydrobenzopyrans (chromans). The reaction involves the formal inverse electron demand [4 + 2] cycloaddition reaction of in situ-generated cationic aryl 2-oxadiene oxocarbenium ions with alkenes. The oxonium ion intermediates are generated through Lewis acid (SnCl4)-promoted reactions of phenol-derived Rychnovsky-type mixedacetals. The yield and diastereoselectivity of the
